Continuous Response Monitoring of Relative Time-to-Contact Judgments: Does Effective Information Change During an Approach Event?

In many previous studies of time-to-contact (TTC) judgments of approaching objects, a response was measured after observers viewed the entire event and was used to infer the informational basis for the judgment. Such measures primarily reflect the information used at the end of the approach event and may not reveal whether observers used different information at different times during the event. Evidence indicates that observers use multiple information sources and that the effectiveness of information varies with distance. We introduce a method in which observers continuously report which of 2 approaching objects would reach them first, throughout the approach. We identified the occurrence and time of response reversals. Most observers changed their relative TTC judgments during the event. The pattern of responses indicated that observers did not use tau early during the approach when objects were far and did not use optical size later when the objects were closer. Most observers relied on either optical size or optical expansion rate early during the approach and expansion rate later during the event, although there were individual differences. A single relative TTC judgment measured after observers view an approach event may not reflect judgments or their informational basis throughout the entire event.     

Dyadic Examination of the Influence of Family Relationships on Life Satisfaction at the Empty-Nest Stage

The aim of this study on determinants of life satisfaction in adulthood was to test actor–partner interdependence models among couples in the phase of the family life cycle following the departure of their children from the parental home. Using structural equation modeling, measures of family relationships, such as a person’s own and his/her partner’s marital adjustment, the amount of contact with children (and grandchildren, if applicable), and being a grandparent or not, served as independent variables to predict each partner’s satisfaction with life. A sample comprising 102 couples (of which 58 couples had grandchildren), all at the empty-nest stage, participated in the study. Results revealed that, for both husbands and wives, the effects of their own marital adjustment and the amount of contact with their adult children on their satisfaction with life were significant. A partner effect was also confirmed between wives’ marital adjustment and their husbands’ satisfaction with life. Furthermore, although being a grandparent did not predict higher life satisfaction for the whole sample of couples, the path between the amount of contact with grandchildren and life satisfaction was significant for the subsample of women who were grandmothers. Results are discussed in terms of the needs filled by these family relationships.     

Longitudinal relationships between workplace bullying,basic psychological needs,and employee functioning: a simultaneous investigation of psychological need satisfaction and frustration

The aim of this cross-lagged study was to provide new insight into the interplay between workplace bullying, basic psychological needs (for autonomy, competence, and relatedness), and employee functioning. Based on new developments in self-determination theory (SDT) research, we simultaneously examined the temporal relationships between workplace bullying, need satisfaction and frustration, as well as two indicators of psychological functioning: life satisfaction and psychosomatic complaints. Data were collected at two time points over a 12-month period from a sample of 508 Canadian nurses. Results suggest that bullying not only negatively predicted satisfaction for the needs of autonomy and competence, it actively frustrated all three needs. Frustration of the needs for competence and relatedness as well as satisfaction of the need for relatedness also predicted the psychological functioning of employees exposed to bullying behaviour over time. Taken together, the results suggest that evaluating need frustration provides in-depth insight into the detrimental effects of bullying on employees’ psychological inner resources and may explain the impoverishment of employees’ psychological functioning when confronted with bullying behaviour. The implications for the bullying and SDT literature are discussed.     

Reversal learning in gonadectomized marmosets with and without hormone replacement: are males more sensitive to punishment?

This study examined sex differences in executive function in middle-aged gonadectomized marmosets (Callithrix jacchus) with or without hormonal replacement. We tested ten castrated male (mean age 5.5 years) marmosets treated with testosterone cypionate (T, n = 5) or vehicle (n = 5) on Reversal Learning, which contributes to cognitive flexibility, and the Delayed Response task, measuring working memory. Their performance was compared to that of 11 ovariectomized females (mean age = 3.7 years) treated with Silastic capsules filled with 17-β estradiol (E2, n = 6) or empty capsules (n = 5), previously tested on the same tasks (Lacreuse et al. in J Neuroendocrinol 26:296–309, 2014. doi: 10.1111/jne.12147). Behavioral observations were conducted daily. Females exhibited more locomotor behaviors than males. Males and females did not differ in the number of trials taken to reach criterion on the reversals, but males had significantly longer response latencies, regardless of hormone replacement. They also had a greater number of refusals than females. Additionally, both control and T-treated males, but not females, had slower responses on incorrect trials, suggesting that males were making errors due to distraction, lack of motivation or uncertainty. Furthermore, although both males and females had slower responding following an incorrect compared to a correct trial, the sex difference in response latencies was disproportionally large following an incorrect trial. No sex difference was found in the Delayed Response task. Overall, slower response latencies in males than females during Reversal Learning, especially during and following an incorrect trial, may reflect greater sensitivity to punishment (omission of reward) and greater performance monitoring in males, compared to females. Because these differences occurred in gonadectomized animals and regardless of hormone replacement, they may be organized early in life.     

Idiosyncratic Deals and Helping Behavior: The Moderating Role of I-deal Opportunity for Co-workers

Purpose

This study draws from social comparison theory to explore why and under which circumstances individuals receiving idiosyncratic deals (i-deals) are likely to help their co-workers.

Design

Data were collected with an alumni association of engineers. Participants completed two questionnaires (N = 182 at Time 2).

Findings

We find that the relationship between i-deals and helping behavior is not direct, but is mediated by organizational-based self-esteem. This relationship is stronger when i-deal recipients believe that their co-workers do not have the opportunity to get i-deals for themselves.

Implications

I-deal recipients are expected to help their colleagues because helping colleagues is consistent with the positive self developed thanks to i-deals. When co-workers have the opportunity to get i-deals for themselves, social comparison between the i-deal recipient and colleagues is likely to be more salient, which strengthen the indirect relationship between i-deal and helping behavior.

Originality

This study tests i-deals from the vantage point of social comparison theory rather than from the perspective of social exchange. We thereby provide a richer account of the complexities involved in helping behavior. By exploring contextual variables that are likely to trigger social comparisons, we also expect to better understand the circumstances under which i-deals are likely to be associated with helping behavior.

     

The spatiotopic representation of visual objects across time

Each eye movement introduces changes in the retinal location of objects. How a stable spatiotopic representation emerges from such variable input is an important question for the study of vision. Researchers have classically probed human observers' performance in a task requiring a location judgment about an object presented at different locations across a saccade. Correct performance on this task requires realigning or remapping retinal locations to compensate for the saccade. A recent study showed that performance improved with longer presaccadic viewing time, suggesting that accurate spatiotopic representations take time to build up. The first goal of the study was to replicate that finding. Two experiments, one an exact replication and the second a modified version, failed to replicate improved performance with longer presaccadic viewing time. The second goal of this study was to examine the role of attention in constructing spatiotopic representations, as theoretical and neurophysiological accounts of remapping have proposed that only attended targets are remapped. A third experiment thus manipulated attention with a spatial cueing paradigm and compared transsaccadic location performance of attended versus unattended targets. No difference in spatiotopic performance was found between attended and unattended targets. Although only negative results are reported, they might nevertheless suggest that spatiotopic representations are relatively stable over time.     

Everyday‐like memory for objects in ageing and Alzheimer's disease assessed in a visually complex environment: The role of executive functioning and episodic memory

To investigate everyday memory, more and more studies rely on virtual‐reality applications to bridge the gap between in situ approaches and laboratory settings. In this vein, the present study was designed to assess everyday‐like memory from the virtual reality‐based Human Object Memory for Everyday Scenes (HOMES) test (Sauzéon et al., 2012 , Exp. Psychol., 59, 99) in ageing and in Alzheimer's disease (AD). Two aims motivated this study: the first was to assess multiple processes of episodic memory (EM) functioning embedded within contexts closely related to real life in ageing and AD using the multi‐trial free‐recall paradigm, and the second aim was to evaluate the mediating effects of executive functioning (EF), EM, and subjective memory complaints (SMCs) on age differences in the HOMES measures and in AD. To this end, the HOMES test and neurocognitive tests of EF and EM were administered to 23 younger adults, 23 older adults, and 16 patients with AD. The results were: firstly, compared to young adults, elderly adults presented only free‐recall decline that almost disappeared in recognition condition whereas AD patients exhibited a poor clustering, learning, and recognition performance, and also a high amount of false recognition; secondly, age differences as well as AD related deficits on the HOMES test were mediated by both memory and EF measure while those observed on false memory indices were only mediated by EM measure; thirdly, the HOMES indices are related to SMCs even when episodic or EF measures are controlled. Overall, the results supported the fact that the VR‐based memory test is an appropriate device to capture age‐related differences as well as the AD effect with respect to both in situ and laboratory settings.     

Pink for Girls,Red for Boys,and Blue for Both Genders: Colour Preferences in Children and Adults

Colours carry social connotations like pink for girls and blue for boys. In a cross-sectional study, we investigated whether such early gender coding might be reflected in absolute colour preferences in children and adults of both genders. In two studies, participants selected their favourite (and least favourite, Study 2) colour from an unrestricted sample of colours. We tested 129 Swiss children (Study 1, 10–14 years-old, 68 boys) and 180 Swiss adults (Study 2, 17–48 years-old, 88 men). In children, we observed that girls chose pink/purple as their favourite hue more often than boys did, the most common favourite hue in girls and boys was blue, and boys chose red as their favourite more often than girls did. In adults, we observed that both genders almost never choose pink as their favourite, blue was a common favourite colour, and women were more likely to favour red than were men. In an additional study (n?=?183 Swiss participants, 47 men), we tested whether liking of pink, blue, and red was related to emotion associations with these colours. Pink was associated with positive emotions to the same extent as blue and red. Women further associated more positive emotions with pink than did men. We conclude that some commonalities (blue) and gender differences (pink and red) exist in absolute colour preferences. These differences, however, cannot be fully accounted by emotional associations. We speculate about these gendered colour preferences in relation to gender stereotypes and status differences between men and women.
