From gaze cueing to perspective taking: Revisiting the claim that we automatically compute where or what other people are looking at

ABSTRACT

Two paradigms have shown that people automatically compute what or where another person is looking at. In the visual perspective-taking paradigm, participants judge how many objects they see; whereas, in the gaze cueing paradigm, participants identify a target. Unlike in the former task, in the latter task, the influence of what or where the other person is looking at is only observed when the other person is presented alone before the task-relevant objects. We show that this discrepancy across the two paradigms is not due to differences in visual settings (Experiment 1) or available time to extract the directional information (Experiment 2), but that it is caused by how attention is deployed in response to task instructions (Experiment 3). Thus, the mere presence of another person in the field of view is not sufficient to compute where/what that person is looking at, which qualifies the claimed automaticity of such computations.     

Affective evidence that inhibition is involved in separating accessory representations from active representations in visual working memory

ABSTRACT

The multiple state theory of working memory suggests that representations are divided into two states: focused-on active representations and accessory memories held for later use. Here we tested two competing hypotheses regarding the neurocognitive mechanisms responsible for this separation: (1) that accessory memories undergo inhibition or (2) that accessory memories are amplified less than active representations. We explored whether accessory memories undergo affective devaluation, a known index of the involvement of inhibition in a visual task. On each trial participants memorized four items, were cued to focus on one, and then completed a visual search or an affective evaluation task. While search distractors matching the colour of an active item slowed search, those matching an accessory memory did not, replicating previous findings that only active items guide search. Also, accessory items were affectively devalued compared to baseline and active items, supporting the hypothesis that accessory memories undergo inhibition.     

Effects of test anxiety on motor learning: The processing efficiency hypothesis

Abstract

The hypothesis that, under test (stress) conditions, high trait-anxious individuals invest extra processing resources to reach motor learning levels similar to those of low-anxious individuals was investigated. A transfer procedure (practice trial, rest interval, and transfer trial) was employed to analyse motor learning effects. In Experiment 1, a secondary task (click detection) was used to measure the extra processing resources expenditure on motor learning during the practice trial. Neither motor performance in the transfer trial nor secondary task performance differed as a function of test condition or anxiety trait. A critical analysis of the secondary task paradigm suggested that it was not sensitive enough to reflect the amount of processing capacity expended on the primary motor tasks. In Experiment 2, subjects performed a loading task (verbal shadowing of sentences) concurrently with the motor tasks during the practice trial to prevent extra resources from being allocated to motor learning. Results showed that anxiety trait was associated to performance time increments on the high-demanding motor tasks in the transfer trial. A plausible explanation is that anxiety impairs learning because it reduces the efficiency of processing. An alternative interpretation, concerning an ability deficit of high trait-anxious individuals, is discussed.     

Effects of Backpack Carriage on Dual-Task Performance in Children During Standing and Walking

Primary school children perform parts of their everyday activities while carrying school supplies and being involved in attention-demanding situations. Twenty-eight children (8–10 years old) performed a 1-legged stance and a 10 m walking test under single- and dual-task situations in unloaded (i.e., no backpack) and loaded conditions (i.e., backpack with 20% of body mass). Results showed that load carriage did not significantly influence children's standing and walking performance (all p > .05), while divided attention affected all proxies of walking (all p < .001). Last, no significant load by attention interactions was detected. The single application of attentional but not load demand negatively affects children's walking performance. A combined application of both did not further deteriorate their gait behavior.     

The Impact of Regulatory Fit on Performance in an Inattentional Blindness Paradigm

The influence of timing and frequency of instructions on the reasoning of jurors in a simulated grand larceny trial was investigated. Mock jurors were given definitions of grand larceny before and after the testimony, only before, only after, or not at all. Although timing of instructions was not significantly related to reasoning or to verdicts, frequency of instructions influenced the aspects of testimony deemed relevant and increased juror use of legal rules in making verdicts. Selective encoding of testimony could not account for the instruction effect.     

Skills of Cognitive Flexibility in Monolingual and Bilingual Younger Adults

The current study examined skills of cognitive flexibility and sustained attention in late bilingual and monolingual younger adults. One-hundred and sixty two younger adults aged between 18 and 34 years old (M = 22.39) classified as Turkish-English late bilinguals (N = 74) and Turkish monolinguals (N = 88) completed the Trail Making Test (TMT-A and TMT-B). Results from this study showed that Turkish-English late bilinguals had shorter RTs than Turkish monolinguals on the TMT-B, however there were no significant RT differences between the groups on the TMT-A. These findings indicate that bilingualism impacts upon skills of cognitive flexibility but not sustained attention and that the amount of practice in coordinating, monitoring, and switching between languages is an important determinant of cognitive improvement.     

Differentiating sexual preference in men: Using dual task rapid serial visual presentation task

Cognition research suggests that allocating attention resources to evolutionarily relevant stimuli is facilitated suggesting that sexual stimuli interfere with human information processing. In a group of gay (n = 13) and straight men (n = 13) recruited in Finland, Germany and Italy, we investigated if and how sexually relevant visual stimuli affect information processing of both a target one (T1) and a subsequent target two (T2) in a dual target rapid serial visual presentation procedure. We hypothesized that: (1) due to the attentional blink (AB) phenomenon, the accuracy of reporting of T2 would decrease when following accurately identified sexually preferred T1 compared to accurately identified non‐sexually preferred T1; 2) due to the pop out effect, the accuracy of reporting of T1 and T2 would be relatively increased when T1 and T2 were sexually preferred by the participants compared to when they were not. Our findings did not support hypothesis 1 but supported hypothesis 2. We further found that the pop out effect had a good capacity to differentiate sexual preference between the groups of gay and straight men. We conclude that dual target rapid serial visual presentation can be used as an attention‐based measurement to differentiate sexual preference in men. Limitations and the applicability in the field of measuring sexual preference were discussed.     

So many options,so little control: Abstract representations can reduce selection demands to increase children’s self-directed flexibility

Children often struggle to behave flexibly when they must use self-directed goals (e.g., doing homework without prompting) rather than externally driven goals (e.g., cleaning up when told). Such struggles may reflect the demands of selecting among many potential options, as required for self-directed control. The current study tested whether (a) 6-year-old children show difficulty in selecting among competing semantic representations, (b) providing category labels designed to reduce selection demands improves performance, and (c) such benefits transfer to self-directed flexibility. Selection was measured using the blocked cyclic naming task for the first time with children. Pictures were named repeatedly in either homogeneous blocks from the same category (e.g., all animals), which create high selection demands due to spreading semantic activation and engage effortful cognitive control, or mixed blocks with each picture from a different category. Children showed robust difficulty in selecting among options, as indexed by response time (RT) differences between homogeneous and mixed blocks. Providing subcategory labels designed to reduce selection demands by distinguishing among same-category items (e.g., “A cow is a farm animal. A cat is a pet.”) improved selection. Providing superordinate categories (e.g., “A cow is an animal. A cat is an animal.”) also improved selection, but these benefits were less robust, and subcategory labels led to greater benefits than superordinate category labels on a subsequent verbal fluency task. These results support a role for subcategory representations in reducing selection demands to aid self-directed flexibility while suggesting that some children may use superordinate category labels to activate subcategory representations on their own.
