unitary construct definition psychology

Front Ecol Evol. Epub 2018 Nov 29. Many researchers have taken terms like attention, intention, and decision making from everyday language and expect this linguistic categorization to somehow map to identifiable mechanisms in the brain or functions. The Anatomical Record, 261, 111-125. As we argue below, the human brain can be considered to have many sources of selectivity and, in the end, it is the brain as a whole that does the integration. From three-dimensional space vision to prehensile hand movements: the lateral intraparietal area links the area V3A and the anterior intraparietal area in macaques. 8600 Rockville Pike Hove, England: Psychology Press.

These studies demonstrate there is preferential processing of stimuli at the goal of a saccade just before the onset of the eye movement (presumably because attention has been shifted to the goal location). It also makes an assumption that memories are always circulating to different areas of the brainnever having a definite cortical space that stores the memory. Psychological Research, 71, 22- 29.

The attempt to establish evidence for construct validity inferences is tantamount to theory testing. Most researchers agree that the posterior parietal cortex represents the core of the neural substrate of selective attention, and is a key node of an attentional network (Corbetta & Shulman, 2011; Posner & Dehaene, 1994; Ptak, 2012). (2007). Fagioli, S., Hommel, B., & Schubotz, R. I. To save this word, you'll need to log in. This availability becomes particularly important in primates, which evolved from tree-climbing insect eaters and developed large eyes with a central, high-resolution fovea, and acquired a taste for fruit. 2017. doi:10.1002/9781119132363.ch16.

Lacalli, T. C. (2018). In contrast to modern validity theory, older validity theory described different kinds of validity: content validity, construct validity, and criterion validity. https://doi.org/10.1073/pnas.1104047108, Article Disclaimer. Eysenck, M.W. sharing sensitive information, make sure youre on a federal Constructs are the building blocks of scientific theories.[1]. [3] Working memory includes subsystems that store and manipulate visual images or verbal information, as well as a central executive that coordinates the subsystems. A common network of functional areas for attention and eye movements. 3), where the fraction of spontaneously complemented TEVp fragments is predicted to be higher, clear background activity is also visible. Awh et al. Epub 2021 Dec 7. Part of Springer Nature. System 2 corrects and adjusts the perceptual blindness associated with system 1. Arch Ital Biol. A particularly promising approach is the pre-motor theory, which argues that shifts of attention are triggered by sub-threshold saccadic commands in oculomotor areas and, conversely, shifts of attention in space lead to action planning (e.g., Rizzolatti, Riggio, Dascola, & Umilta, 1987). Neural correlates of memorys successes and sins. Of course, to support useful inferences of criterion-related validity, one must first identify theoretically meaningful criterion constructs (i.e., what types of future behaviors or outcomes should be associated with or influenced by the construct denoted by the predictor measure), as well as ensure that there are measures of criterion constructs for which there is strong content validity evidence. One moose, two moose. Cross-diagnostic determinants of cognitive functioning: the muscarinic cholinergic receptor as a model system. When a cue becomes present, the context vector that the cue points to gets oscillated back to the starting point, where the memory can then be used in short term memory. For example, inferences about individual differences . This may seem an almost trivial point, but it is important to stress that validation is a unitary construct that tests the theory and the measure at the same time [ 17]. n. 1. a complex idea or concept formed from a synthesis of simpler ideas. Presence and Reality Judgment in Virtual Environments: A Unitary Construct?

In D. Corbetta & M. Santello (Eds. Thus, the characteristics of the physically executed action actually reflect the attentional state of the target and non-target stimuli. In S Schneider, M Velmans (Eds), The Blackwell Companion to Consciousness, Second Edition. sharing sensitive information, make sure youre on a federal And yet, after decades of work by some of the worlds most accomplished neuroscientists, a clear dissociation of the function of posterior parietal cortex remains elusive. Bethesda, MD 20894, Web Policies . Indeed, attempts to systematically distinguish the processes underlying attention from the processes that do not, often fail to produce any coherent consensus. Likewise, the synthetic approach explains why sensitivity to different features of objects depends on the action context (Bekkering & Neggers, 2002; Craighero et al., 1999; Fagioli et al., 2007; Welsh & Pratt, 2008) because the context determines which action-centered parietal stream, with its idiosyncratic representation of the external world, is being selectively invigorated at a given time. Importantly, and as required from the view that selectivity for behavioral relevance is the purview of the entire moving body, the superior colliculus is involved not just in eye movements, but in orienting movements of the eye, head, body, and hand (Gandhi & Katnani, 2011; Stuphorn, Hoffmann, & Miller, 1999). The tectum expanded in parallel, with a matched topographic map of space in its superficial layers and gradients of downstream projections in its deep layers. That is, when we measure something, we need to ask whether the measurements we have taken accurately and completely reflect what we intended to measure. The term content validity typically refers to inferences regarding the degree to which the content on a measurement device adequately represents the universe of possible content denoting the targeted construct or performance domain. At face value, it seems highly unlikely that the same set of functional/neural mechanisms are involved in, and responsible for, this broad variety of phenomena (Allport, 1993), and a bulk of behavioral and neural evidence confirms that most subfunctions can be dissociated from each other (e.g., Fan, McCandliss, Sommer, Raz, & Posner, 2002). Experimental Brain Research, 149, 207-213. Behavioral sciences use constructs such as conscientiousness, intelligence, political power, self-esteem, and group culture. Verywell Mind articles are reviewed by board-certified physicians and mental healthcare professionals. A psychological construct is a label for a domain of behaviors. Mating systems, such as monogamy, are the product of the behavioral patterns displayed by individual organisms. Before we explain our main position and arguments, we would like to emphasize that the theoretical problems that we highlight are particularly visible with respect to the concept of attention, but by no means restricted to that concept (Hommel, 2019a). In other situations, however, different fronto-parietal streams will be coordinated. PubMed Visual search is modulated by action intentions. In a sense, each circuit was an action map analogous to the much older tectal systems for approach and avoidance, but guiding the much wider repertoire of task-specific interactions available in the mammalian niche. It involves an elevated state of awareness where people are able to gain a greater sense of themselves, their role, and the world. 1). B. ), Attention and performance XV. Buneo, C. A., Jarvis, M.

Behavioral sciences use constructs such as conscientiousness, intelligence, political power, self-esteem, and group culture. Welsh, T.N., & Pratt, J. Researchers continue to explore the different bases of consciousness including the physical, social, cultural, and psychological influences that contribute to our conscious awareness. Changes to consciousness also can cause changes to perception, thinking, understanding, and interpretations of the world. Cutrell, E. B., & Marrocco, R. T. (2002). suggest solving this problem by adding a third variable selection history to the list of factors. ), and whether attention is a concept that refers to the problem or to the solution. The Well-Being Index scale (WHO-5) is a generic, self-report scale that contains five Likert-type items to evaluate psychological well-being. Cognition, 116, 168-176. Snyder, L.H., Grieve, K.L., Brotchie, P., & Andersen, R.A. (1998). For instance, in the study of the asymmetry in decisions to go for a good option versus avoid a bad one, participants were biased toward positively valanced targets 100 ms earlier than they were biased to move away from negative ones (Chapman et al., 2015b). 183218. In the lineage leading to vertebrates, the photosensitive patch split into two lateral eye patches on both sides of the head (Butler, 2000). Journal of Vision, 14, 30-30. Rubin LH, Han J, Coughlin JM, Hill SK, Bishop JR, Tamminga CA, Clementz BA, Pearlson GD, Keshavan MS, Gershon ES, Heilman KJ, Porges SW, Sweeney JA, Keedy S. Schizophr Res. Tail and eye movements evoked by electrical microstimulation of the optic tectum in goldfish. Hove, England: Psychology Press. Thus, the nature and the influence of reward is itself dependent on numerous contextual factors and the expression of the confluence of these factors is not easily captured in a unitary construct. 3). This search can be hindered by overreliance on "monogamy" conceived as a unitary characteristic. In their case, endogenous and exogenous control were insufficient to account for the variety of pheomenena being ascribed to the concept of attention, so they added selection history. Within each of these fronto-parietal action streams, target selection occurs through winner-take-all dynamics taking place in an idiosyncratic spatial reference frame specific to each given type of action (e.g., retinotopic for eye movements). Johnson, P. B., Ferraina, S., Bianchi, L., & Caminiti, R. (1996). This does not imply, and actually logically undermines, the sometimes observed tendency to consider neural explanations as somehow more fundamental or causal than functional explanations. (2008). Experimental Brain Research, 105, 261-275. Herrero, L., Rodriguez, F., Salas, C., & Torres, B. Journal of Experimental Child Psychology, 3, 177-187. with separable functional and neural processes, and the concentration of research on tasks and subfunctions rather than actual processes. (2019b). 2021 Jul;27-28:10.1016/j.pmip.2021.100078. Specifically, current definitions tend to suggest that intelligence is the ability to: Learn from experience: The acquisition, retention, and use of knowledge is an important component of intelligence. These changes define the limit of associative learning and the threshold of explicit cognition. Salience, relevance, and firing: A priority map for target selection. Given that this integration is the explanandum (the to-be-explained phenomenon), postulating the existence of one map that has no other function than achieving this integration seems to be one more attempt to explain a psychological phenomenon by positing the existence of a dedicated system whose only purpose is to somehow create that phenomenon. Wu, W. (2014). Kendra Cherry, MS,is the author of the "Everything Psychology Book (2nd Edition)"and has written thousands of articles on diverse psychology topics. In early mammals (300 Mya), this system was probably quite limited and consisted simply of medial circuits concerned with locomotion and lateral circuits concerned with head and mouth movements (Kaas, 2017). (2012), one reason is that selection history overlaps considerably with goal-induced endogenous selectivity and salience-induced exogenous selectivity. For example, the synthetic approach can account for harm avoidance. But it does not follow from these correlations that there exists anything in the brain that can be meaningfully delineated as an attentional system (or, for that matter, an intention system or decision system).

Selection history is itself decomposable into (at least) selection and reward history, and reward history is itself decomposable even further. Dynamic allocation of visual attention during the execution of sequences of saccades. Journal of Neurology, 243, 652657. For example, sudden changes in consciousness might be a sign of: If you thinking you are experiencing changes in consciousness, talk to your doctor. Science, 334, 10911097. Careers. Instead, validity is best thought of as a unitary concept addressing how completely and accurately a measure measures what it is intended to measure. Aboitiz, F., & Montiel, J. F. (2015). Support for the former idea has come from a large number of observations including: (a) behavioral studies showing that attention and eye movements are strongly linked behaviorally (e.g., Deubel & Schneider, 1996; Kowler, Anderson, Dosher, & Blaser, 1995; Sheliga, Riggio, & Rizzolatti, 1995); (b) fMRI studies of visual attention showing activation in eye-movement areas for attention tasks (e.g., Beauchamp, Petit, Ellmore, Ingeholm, & Haxby, 2001; Corbetta et al., 1998; Nobre, Sebestyen, & Miniussi, 2000) and for movement activation (decoding) in retinotopically defined visual cortex during movement tasks (Gallivan, Chapman, Gale, Flanagan, & Culham, 2019); (c) stimulation studies showing that activation of neurons in the superior colliculus (SC), frontal eye field (FEF), and lateral intraparietal area (LIP) can change the focus of attention (Cavanaugh & Wurtz, 2004; Cutrell & Marrocco, 2002; Moore & Fallah, 2001; Muller, Philiastides, & Newsome, 2005); and (d) neurological studies of patients with attentional disorders following damage to the frontal cortex, parietal cortex, or midbrain (e.g., Husain & Kennard, 1996; Posner, Cohen, & Rafal, 1982; Posner, Rafal, Choate, & Vaughan, 1985; Sapir, Soroker, Berger, & Henik, 1999). Corbetta, M., & Shulman, G. L. (2011). Validity has recently been reconceptualized as a unitary factor known as constructvalidity. The more important question, therefore, is not if the unitary construct of empathy is related to agreeableness but rather what are the associations between agreeableness and the facets of empathy. Thura, D. & P. Cisek (2014). You can help Wikipedia by expanding it. NewYork, NY: Oxford University Press. Both rates are implausible, as a constant rate of decay neglects all external factors that may contribute to a faster rate of decay (e.g. Cronbach, L. J., & Meehl, P. E. (1955). What is the highest form of consciousness? Experience and net worth affects optimality in a motor decision task. 2023 Dotdash Media, Inc. All rights reserved. Models, movements, and minds: bridging the gap between decision making and action. Nairne, J., & Neath, I. Worth Publishers; 2010. On the other hand, Unitary Theories have more trouble explaining situations where short term memory differs such as the word length effect,[9] which can be more easily explained by the Working Memory model. Higher states of consciousness are often associated with spiritual or mystical experiences. The evolutionary history of spatial interaction along the primate lineage is a long and complex tale (Fig. Attention and effort. Criterion-related validity refers to the degree to which the observed scores can be used to make useful inferences (i.e., accurate predictions) about future behavior or outcomes. Mountcastle, V. B., Lynch, J. C., Georgopoulos, A. P., Sakata, H., & Acuna, C. (1975). Cues become associated with a memory and can later be used to retrieve memories from long term storage. The question is not whether the posterior parietal cortex plays a role in something called attention or something else called intention, but how the posterior parietal cortex fits within a broader system that enables animals to select and control interactions with their environment to achieve their goals and avoid negative outcomes. How Does Implicit Bias Influence Behavior? The history of distinguishing between endogenous and exogenous attention is very similar to the distinction between attention and intention. Kardamakis, A. Furthermore, the rate of decay is much faster in short-term memory as opposed to long-term memory. 2017 Oct 11;8:265. doi: 10.3389/fendo.2017.00265. Having the quality of oneness. 2023 Springer Nature Switzerland AG. Psychological Bulletin, 52, 281-302. Song, J.H., & Nakayama, K. (2008). (2012) tried to solve: the definition of the concept under investigation is too restricted. Deficits in reach target selection during inactivation of the midbrain superior colliculus. Correspondence to For instance, the fact that planning and carrying out particular kinds of actions systematically facilitates the processing of particular object features (e.g., of size and orientation for grasping, location for reaching: Bekkering & Neggers, 2002; Craighero et al., 1999; Fagioli et al., 2007) is unlikely to be genetically determined, but rather the consequence of learning and experience of selecting different features for grasping over the lifespan (Hommel, 2010). Neuron, 31, 889-901. (1996). Essentially, your consciousness is your awareness of yourself and the world around you. Attentional networks. Kyle CJ, Karels TJ, Davis CS, Mebs S, Clark B, Strobeck C, Hik DS. ), Perspectives on perception and action (pp. This ever-shifting stream of thoughts can change dramatically from one moment to the next, but your experience of it seems smooth and effortless. The Oscillator Based Associative Recallolation (OSCAR) Model was proposed by Browne, Preece and Hulme in 2000 [7] The OSCAR Model is another cue driven model of memory. 2012 Mar 30;196(1):38-44. doi: 10.1016/j.psychres.2011.08.021. Researchers are right to pursue these as multiple explananda, but would be wrong to seek or be forced to rule out only one explanans. PubMed Current Opinion in Neurology, 20, 381-386. Attention is a sterile concept; iterative reentry is a fertile substitute. To escape this rather uncomfortable state of affairs, some researchers have argued for a more integrative view on attention and intention. We point out that the concept has too many meanings to justify a single term, and that attention is used to refer to both the explanandum (the set of phenomena in need of explanation) and the explanans (the set of processes doing the explaining). Cambridge, MA: MIT Press. One slave system, the phonological loop (PL), stores phonological information (that is, the sound of language) and prevents its decay by continuously articulating its contents, thereby refreshing the information in a rehearsal loop. Evolution of phototransduction, vertebrate photoreceptors and retina. However, no single method or strategy can provide all the evidence needed to make accurate or confident inferences. Fitts Law and action-centred reference frames in selective reaching: The proximity-to-hand effect revisited. To bolster our analysis of the state of affairs, we present two test cases. (1999). New York: Houghton Mifflin Harcourt. A., & Song, J. H. (2015). The latter includes parts of the lateral prefrontal cortex, orbitofrontal cortex, and all of the limbic cortex and the temporal lobe.

I love the desktop app, its always running on my Mac. Thick lines indicate the presence of relevant fossil data (paleobiodb.org). We hope to bring you new and interesting content on our YouTube channel. FOIA stress, focusing attention on other things). For instance, the term attention is used to refer to the consequences of both voluntary and involuntary factors in favoring the representation of one event having a stronger impact on decision making and action than representations of other events (e.g., Yantis, 1998). Frontiers in Neuroanatomy, 6, 9. Wispinski, N. J., Truong, G., Handy, T. C., & Chapman, C. S. (2017). In an analytic approach to science, one runs the risk of becoming a slave to the concepts that have been generated. Behavioral characteristics of pair bonding in the black tufted-ear marmoset (, Physical separation from the mate diminishes male's attentiveness towards other females: a study in monogamous prairie voles. Pashler, H., & Johnston, J. C. (1998). In psychology, constructs are ways to describe patterns of behaviour or experiences so that they can be explored, investigated, and discussed. Trends in Neuroscience, 17, 75-79. All of these use information on object identity and outcome value, computed in the ventrolateral regions (red arrows), to select the actions most relevant given the current behavioral context. 2018 Nov;93(4):1795-1812. doi: 10.1111/brv.12421. Krauzlis, R.J, Bollimunta, A., Arcizet, F., & Wang L. (2014). unitary construct. In this article, we challenge the usefulness of attention as a unitary construct and/or neural system. The feature model was first described by Nairne (1990)[2] The primary feature of this model is the use of cues for both short term memory and long term memory. The distinction fails to provide a meaningful contribution or framework for sorting the available findings into useful categories to stimulate further theorizing, and it also clashes with the demonstration of so many interactions between input processing and output generation.
