#1
Andrew B Slifkin, Jeffrey R Eder
According to dominant theories of motor control, speed and accuracy are optimized when, on the average, movement endpoints are located at the target center and when the variability of the movement endpoint distributions is matched to the width of the target (viz., Meyer, Abrams, Kornblum, Wright & Smith, 1988). The current study tested those predictions. According to the speed-accuracy trade-off, expanding the range of variability to the amount permitted by the limits of the target boundaries allows for maximization of movement speed while centering the distribution on the target center prevents movement errors that would have occurred had the distribution been off center...

Dynamic interceptive actions are performed under severe spatial and temporal constraints. Here, behavioral processes underpinning anticipation in one-handed catching were examined using novel technology to implement a spatial and temporal occlusion design. Video footage of an actor throwing a ball was manipulated to create four temporal and five spatial occlusion conditions. Data from twelve participants' hand kinematics and gaze behaviors were recorded while attempting to catch a projected ball synchronized with the video footage...

Hanna Fleig, Thorsten Meiser, Florence Ettlin, Jan Rummel
Pseudocontingencies denote contingency estimates inferred from base rates rather than from cell frequencies. We examined the role of statistical numeracy for effects of such fallible but adaptive inferences on choice behavior. In Experiment 1, we provided information on single observations as well as on base rates and tracked participants' eye movements. In Experiment 2, we manipulated the availability of information on cell frequencies and base rates between conditions. Our results demonstrate that a focus on base rates rather than cell frequencies benefits pseudocontingency effects...

The rate of selecting different options in the decisions-from-feedback paradigm is commonly used to measure preferences resulting from experiential learning. While convergence to a single option increases with experience, some variance in choice remains even when options are static and offer fixed rewards. Employing a decisions-from-feedback paradigm followed by a policy-setting task, we examined whether the observed variance in choice is driven by factors related to the paradigm itself: Continued exploration (e...

This study assessed whether specific eye movement patterns are observed during emotional autobiographical retrieval. Participants were asked to retrieve positive, negative and neutral memories while their scan path was recorded by an eye-tracker. Results showed that positive and negative emotional memories triggered more fixations and saccades but shorter fixation duration than neutral memories. No significant differences were observed between emotional and neutral memories for duration and amplitude of saccades...

Nicolas Gauvrit, Fernando Soler-Toscano, Alessandro Guida
In two experiments, Friedenberg and Liby (2016) studied how a diversity of complexity estimates such as density, number of blocks, GIF compression rate and edge length impact the perception of beauty of semi-random two-dimensional patterns. They concluded that aesthetics ratings are positively linked with GIF compression metrics and edge length, but not with the number of blocks. They also found an inverse U-shaped link between aesthetic judgments and density. These mixed results originate in the variety of metrics used to estimate what is loosely called "complexity" in psychology and indeed refers to conflicting notions...

Tony Thomas, Meera Mary Sunny
Many recent studies have reported altered visual processing near the hands. However, there is no definitive agreement about the mechanisms responsible for this effect. One viewpoint is that the effect is predominantly attentional while others argue for the role of pre-attentive perceptual differences in the manifestation of the hand-proximity effect. However, in most of the studies pre-attentional and attentional effects have been conflated. We argue that it is important to dissociate the effect of hand proximity on perception and attention to better theorize and understand how visual processing is altered near the hands...

#8
David Dignath, Markus Janczyk, Andreas B Eder
According to theoretical accounts of cognitive control, conflict between competing responses is monitored and triggers post conflict behavioural adjustments. Some models proposed that conflict is detected as an affective signal. While the conflict monitoring theory assumed that conflict is registered as a negative valence signal, the adaptation by binding model hypothesized that conflict provides a high arousal signal. The present research induced phasic affect in a Simon task with presentations of pleasant and unpleasant pictures that were high or low in arousal...

This study investigated the mechanisms of the numerosity coding of random and regular dot distribution patterns. Experiment 1 revealed that connectedness significantly affected the numerosity perception of randomly distributed dots, and two adjacent dots were considered to be one numeral unit when connected via lines. The connectedness effect was much weaker on the numerosity perception of regularly distributed dots in vertical or horizontal queues and was absent in the perception of dots in diagonal queues...

#10
Lauren D Grant, Daniel H Weissman
Prior findings suggest that coping with distraction relies on cognitive control processes that increase attention to task-relevant processing and/or decrease attention to task-irrelevant processing. In line with this view, the size of the congruency effect in unimodal Stroop-like tasks, a popular measure of distraction, is typically reduced after more distracting incongruent trials relative to after less distracting congruent trials. It remains unclear, however, whether, and under what conditions, the control processes underlying this congruency sequence effect (CSE) minimize cross-modal distraction...

PURPOSE: The Verifiability Approach (VA) is verbal lie detection tool that has shown promise when applied to insurance claims settings. This study examined the effectiveness of incorporating a Model Statement comprised of checkable information to the VA protocol for enhancing the verbal differences between liars and truth tellers. METHOD: The study experimentally manipulated supplementing (or withholding) the VA with a Model Statement. It was hypothesised that such a manipulation would (i) encourage truth tellers to provide more verifiable details than liars and (ii) encourage liars to report more unverifiable details than truth tellers (compared to the no model statement control)...

Prior research has demonstrated that explicit pre-cues informing participants of the proportion congruence of an upcoming list of Stroop trials affect performance in mostly congruent lists but not mostly incongruent lists. This pattern suggests a limited role for expectations in influencing Stroop performance. An alternative explanation, however, is that the effects of pre-cues may be masked by a bleed-over of awareness (of the proportion congruence manipulation) from cued to uncued lists given use of a within-subjects manipulation of cueing in prior research...

This study consisted of two primary aims: (1) to determine if different age groups exhibited different strategies (based on their behavioral reaction time [RT] patterns) while performing a stop-signal task and (2) whether there were age-related differences in reactive and/or proactive control processes. Twenty-four younger adults (20-30years) and 24 older adults (61-76years) participated in this study. Participants performed a stop-signal task, which included a choice RT block, global stop-signal block, and stimulus-selective stop-signal block...

This study investigated relations between judgments of passage of time and judgments of long durations in everyday life with an experience sampling method. Several times per day, the participants received an alert via mobile phone. On each alert, at the same time as reporting their experience of the passage of time, the participants also estimated durations, between 3 and 33s in Experiment 1, and between 2 and 8min in Experiment 2. The participants' affective states and the difficulty and attentional demands of their current activity were also assessed...

The current study examined the augmentation of error feedback on visuomotor adaptability in older adults with varying degrees of cognitive decline (assessed by the Montreal Cognitive Assessment; MoCA). Twenty-three participants performed a center-out computerized visuomotor adaptation task when the visual feedback of their hand movement error was presented in a regular (ratio=1:1) or enhanced (ratio=1:2) error feedback schedule. Results showed that older adults with lower scores on the MoCA had less adaptability than those with higher MoCA scores during the regular feedback schedule...

We sometimes fail to notice unexpected objects or events when our attention is directed elsewhere, a phenomenon called inattentional blindness. We explored whether unexpected objects that shared the color of consequential objects would be noticed more often. In three pre-registered experiments, participants played a custom video game in which they avoided both low- and high-cost missiles (Experiment 1 and 2) or tried to hit rewarding missiles while avoiding costly ones (Experiment 3). After participants had played the game for about 8min, an unexpected object moved across the screen...

Imitation can be realized via two different routes: a direct route that translates visual input into motor output when gestures are meaningless or unknown, and a semantic route for known/meaningful gestures. Young infants show imitative behaviours compatible with the direct route, but little is known about the development of the semantic route, studied here for the first time. The present study examined preschool children (3-5years of age) imitating gestures that could be transitive or intransitive, and meaningful or meaningless...

This research was designed to replicate and extend findings concerning bidirectional interference between concurrent timing and inhibition tasks reported previously. Subjects performed serial temporal production and Go/No-Go (GNG) tasks under single-task and dual-task conditions in two experiments. The degree of inhibitory control required in the GNG tasks was manipulated by varying the proportion of go and no-go stimuli (experiment 1) and by instructing subjects to devote different amounts of attention to the dual tasks (experiment 2)...

Synaesthesia is the neuropsychological phenomenon in which individuals experience unusual sensory associations, such as experiencing particular colours in response to particular words. While it was once thought the particular pairings between stimuli were arbitrary and idiosyncratic to particular synaesthetes, there is now growing evidence for a systematic psycholinguistic basis to the associations. Here we sought to assess the explanatory value of quantifiable lexical association measures (via latent semantic analysis; LSA) in the pairings observed between words and colours in synaesthesia...

Gaze plays a pivotal role in human communication, especially for coordinating attention. The ability to guide the gaze orientation of others forms the backbone of joint attention. Recent research has raised the possibility that gaze following behaviors could induce liking. The present study seeks to investigate this hypothesis. We designed two physically different human avatars that could follow the gaze of users via eye-tracking technology. In a preliminary experiment, 20 participants assessed the baseline appeal of the two avatars and confirmed that the avatars differed in this respect...
