Recent perspectives for the study of perceptual-motor expertise have highlighted the importance for considering variability in gaze behaviour. The present paper explores the prevalence of variability in gaze behaviour in an anticipation task through examining goalkeepers gaze behaviours when saving soccer penalty kicks, with a primary focus on offering new considerations for the study of variability in gaze behaviour. A subset of data from five goalkeepers in the previously published article of Dicks et al. ((2010) Attention, Perception, & Psychophysics, 72(3), 706–720) were reanalysed, with a focus on ten successful penalty saves for each goalkeeper. As the aim was to conduct exploratory analyses of individual differences in goalkeeping performance, data were not averaged across participants and instead intra- and inter-individual differences are described using descriptive statistics. The main observation was that variation in the goalkeepers’ gaze behaviours existed and were evident both between and within individuals, specifically with regards to quiet eye duration but also for percentage viewing time and visual search patterns. However, QE location appeared to represent the only invariant gaze measure with the location being on the ball for the majority of trials. The current exploratory analysis suggested that experienced goalkeepers did not converge on the same gaze patterns during successful anticipation performance. The implications of these findings are discussed in relation to extant gaze behaviour literature before considering implications for future research.

AbstractActive visual scanning of the scene is a key task-element in all forms of human locomotion. In the field of driving, steering (lateral control) and speed adjustments (longitudinal control) models are largely based on drivers’ visual inputs. Despite knowledge gained on gaze behaviour behind the wheel, our understanding of the sequential aspects of the gaze strategies that actively sample that input remains restricted. Here, we apply scan path analysis to investigate sequences of visual scanning in manual and highly automated simulated driving. Five stereotypical visual sequences were identified under manual driving: forward polling (i.e. far road explorations), guidance, backwards polling (i.e. near road explorations), scenery and speed monitoring scan paths. Previously undocumented backwards polling scan paths were the most frequent. Under highly automated driving backwards polling scan paths relative frequency decreased, guidance scan paths relative frequency increased, and automation supervision specific scan paths appeared. The results shed new light on the gaze patterns engaged while driving. Methodological and empirical questions for future studies are discussed.

Abstract The number of sexual minority (SM) older adults is increasing rapidly, yet this population continues to be underrepresented in research (Fredriksen-Goldsen & Kim, 2017) and experiences significant disparities in health and health care access (Fredriksen-Goldsen, 2016; Wallace et al., 2011). In the current symposium, we analyze data from U.S. national probability samples of middle-aged and older adults (MIDUS, HRS, NESARC-III) to consider how age-related concerns and challenges may be experienced differently by SM individuals compared to their heterosexual counterparts. This symposium includes novel methods and statistical tools, such as daily diary assessments, multilevel modeling, and time-varying effects models. Individual presentations evaluate how: (1) SM women, compared to heterosexual women, may respond differently to menopause through norms and values surrounding womanhood; (2) midlife and older SM individuals use alcohol and cigarettes more frequently across a typical week than their heterosexual counterparts, though their substance use may not be tied to common triggers (e.g., negative mood, stress); (3) despite bisexual older adults reporting more health problems compared to lesbian and gay counterparts, they are less prepared for health concerns and crises (e.g., reporting a lower number of valid wills); and (4) the prevalence of depression and anxiety varies across age, such that older SM adults—especially women—are particularly vulnerable to psychological health problems. These presentations collectively examine complex issues facing older SM adults while emphasizing individual differences (i.e., women’s concerns, bisexual people’s issues). We discuss challenges in researching this growing at-risk population, and we highlight areas of future research and intervention.

How do valenced odors affect the perception and evaluation of facial expressions? We reviewed 25 studies published from 1989 to 2020 on cross-modal behavioral effects of odors on the perception of faces. The results indicate that odors may influence facial evaluations and classifications in several ways. Faces are rated as more arousing during simultaneous odor exposure, and the rated valence of faces is affected in the direction of the odor valence. For facial classification tasks, in general, valenced odors, whether pleasant or unpleasant, decrease facial emotion classification speed. The evidence for valence congruency effects was inconsistent. Some studies found that exposure to a valenced odor facilitates the processing of a similarly valenced facial expression. The results for facial evaluation were mirrored in classical conditioning studies, as faces conditioned with valenced odors were rated in the direction of the odor valence. However, the evidence of odor effects was inconsistent when the task was to classify faces. Furthermore, using a z-curve analysis, we found clear evidence for publication bias. Our recommendations for future research include greater consideration of individual differences in sensation and cognition, individual differences (e.g., differences in odor sensitivity related to age, gender, or culture), establishing standardized experimental assessments and stimuli, larger study samples, and embracing open research practices.

Search Patterns

This investigation analyzed the visual search patterns of novice and expert dance teachers when viewing a live performance of a dance composition. The hypotheses tested were that (a) experts would not differ from novices in the number of eye fixations and duration of each, (b) the number of fixations and duration of each would differ between dances, and (c) expert teachers’ search patterns would differ from those of novice teachers. The subjects were four experts who averaged 25.5 years of teaching, and five novice teachers who averaged 2.4 years. To determine the ocular fixation and scanning patterns of subjects, the NAC Eye Movement Recorder, a corneal reflection technique, was used. The films were analyzed using a computer program designed to collect the data. Two 2 × 2 (expertise and dances) analyses of variance were used to determine the differences in the number of fixations, duration of fixations, and differences of variable between dances. Chi-square was used to determine the location of scan patterns. Results indicated that the level of expertise did not influence the number or duration of each eye fixation, but the task being observed did influence these variables. Individual differences in visual scanning patterns were found among and within both groups.

AbstractInvoluntary musical imagery (INMI) refers to a conscious mental experience of music that occurs without deliberate efforts to initiate or sustain it. This experience often consists of the repetition of a short fragment of a melody, colloquially called an “earworm.” Here, we present the first comprehensive, qualitative review of published empirical research on INMI to date. We performed an extensive literature search and discovered, in total, 47 studies from 33 peer-reviewed articles that met the inclusion criteria for the review. In analyzing the content of these studies, we identified four major research themes, which concern the phenomenology, dynamics, individual differences, and musical features of INMI. The findings answer many questions of scientific interest—for instance, what is typical in terms of INMI frequency, duration, and content; which factors influence INMI onset; and whether demographic and personality factors can explain individual differences in susceptibility and responses to INMI. This review showcases INMI as a well-established phenomenon in light of a substantial body of empirical studies that have accumulated consistent results. Although the populations under study show an unfavorable bias towards Western, educated participants, the evidence depicts INMI as a universal psychological phenomenon, the possible function of which we do not yet fully understand. The concluding section introduces several suggestions for future research to expand on the topic.

Reach Planning

Successful motor performance relies on our ability to adapt to changes in the environment by learning novel mappings between motor commands and sensory outcomes. Such adaptation is thought to involve two distinct mechanisms: an implicit, error-based component linked to slow learning and an explicit, strategic component linked to fast learning and savings (i.e., faster relearning). Because behavior, at any given moment, is the resultant combination of these two processes, it has remained a challenge to parcellate their relative contributions to performance. The explicit component to visuomotor rotation (VMR) learning has recently been measured by having participants verbally report their aiming strategy used to counteract the rotation. However, this procedure has been shown to magnify the explicit component. Here we tested whether task-specific eye movements, a natural component of reach planning, but poorly studied in motor learning tasks, can provide a direct readout of the state of the explicit component during VMR learning. We show, by placing targets on a visible ring and including a delay between target presentation and reach onset, that individual differences in gaze patterns during sensorimotor learning are linked to participants’ rates of learning and their expression of savings. Specifically, we find that participants who, during reach planning, naturally fixate an aimpoint rotated away from the target location, show faster initial adaptation and readaptation 24 h later. Our results demonstrate that gaze behavior cannot only uniquely identify individuals who implement cognitive strategies during learning but also how their implementation is linked to differences in learning. NEW & NOTEWORTHY Although it is increasingly well appreciated that sensorimotor learning is driven by two separate components, an error-based process and a strategic process, it has remained a challenge to identify their relative contributions to performance. Here we demonstrate that task-specific eye movements provide a direct read-out of explicit strategies during sensorimotor learning in the presence of visual landmarks. We further show that individual differences in gaze behavior are linked to learning rate and savings.

Marijuana Consumption

Prior research has shown that young people are more likely to say no to a peer group's drug or alcohol consumption when they also ask why. That is, being able to explain peer substance abuse, especially in terms of normative motives, has been associated with reduced conformity. The authors show that individual differences based on prior attitudes toward illicit consumption and susceptibility to social influence are useful for segmenting young people to better target and design effective intervention strategies. Results from Studies 1 and 2 indicate that prior attitude toward marijuana consumption and reported marijuana usage affect the explanations made to account for a peer group's substance abuse. In Study 2, the association between normative explanations for peer marijuana use and intentions to smoke marijuana is shown to depend on susceptibility to social influence. The implications of these findings for future research and for public policy are also discussed.

Anatomical Trait

Abstract. The second-to-fourth digit ratio (2D:4D), an inconspicuous, but sexually differentiated anatomical trait (men present lower 2D:4D than women), has received intense research interest recently. Fairly strong evidence points to 2D:4D as a biomarker for the organizational (permanent) effects of prenatal testosterone on the brain and behavior. 2D:4D has been shown to be a correlate of a wealth of sex-dependent, hormonally influenced traits and phenotypes, which reach into the domains of behavior, fertility, health, physique, sexuality, and sports and also deeply into differential psychology (ability, cognition, and personality). This study investigated whether individual differences in 2D:4D are related to individual differences in attractiveness, sex typicality, and other attributes ascribed to palm images by raters. For both sexes, more sex-atypical trait expressions (i.e., higher 2D:4D in male, but lower 2D:4D in female palm specimens) were related to higher aggregate ratings of attractiveness, healthiness, sexiness, imagined handshake pleasantness, and imagined person dominance, albeit only the last association achieved formal statistical significance with two-tailed testing. These findings suggest that 2D:4D might be a correlate of perceived dominance and possibly also of other attributes. Digit ratio associations with sex-typicality ratings (sex-of-hand judgments and perceived palm masculinity and femininity) were inconsistent and mostly of smaller size. Finger lengths (2D and 4D) were generally more strongly and consistently related to palm attributes than 2D:4D was. Implications of the findings, study limitations, and directions for future research are considered.
