Reward anticipation enhances brain activation during response inhibition

The chance to achieve a reward starts up the required neurobehavioral mechanisms to adapt our thoughts and actions in order to accomplish our objective. However, reward does not equally reinforce everybody but depends on interindividual motivational dispositions. Thus, immediate reward contingencies can modulate the cognitive process required for goal achievement, while individual differences in personality can affect this modulation. We aimed to test the interaction between inhibition-related brain response and motivational processing in a stop signal task by reward anticipation and whether individual differences in sensitivity to reward (SR) modulate such interaction. We analyzed the cognitive–motivational interaction between the brain pattern activation of the regions involved in correct and incorrect response inhibition and the association between such brain activations and SR scores. We also analyzed the behavioral effects of reward on both reaction times for the “go” trials before and after correct and incorrect inhibition in order to test error prediction performance and postinhibition adjustment. Our results show enhanced activation during response inhibition under reward contingencies in frontal, parietal, and subcortical areas. Moreover, activation of the right insula and the left putamen positively correlates with the SR scores. Finally, the possibility of reward outcome affects not only response inhibition performance (e.g., reducing stop signal reaction time), but also error prediction performance and postinhibition adjustment. Therefore, reward contingencies improve behavioral performance and enhance brain activation during response inhibition, and SR is related to brain activation. Our results suggest the conditions and factors that subserve cognitive control strategies in cognitive motivational interactions during response inhibition.

Estimating Coefficients of Equivalence and Stability for Job Performance Ratings: The importance of controlling for transient error on criterion measurement

Previous research on measurement error in job performance ratings estimated reliability using coefficients: alpha, test–retest, and interrater correlation. None of these three coefficients control for the four main sources of error in performance ratings. For this reason, coefficient of equivalence and stability (CES) has been suggested as the ideal estimate of reliability. This article presents the estimates of CES for a time interval of 1, 2, and 3 years. The values obtained for a single rater were .51, .48, and .44, respectively. For two raters, the values were .59, .55, and .51. The findings suggest that previous reliability estimates based on alpha, test–retest, and interrater coefficients overestimated the reliability of job performance ratings. In the present study, the interrater coefficient overestimates reliability by 13.6–25.4% for an interval time of 1–3 years, as it does not control for transient error. Results also showed that the importance of transient error increases as the length of the interval between the measures increases. Based on the results, it is suggested that corrected validities based on interrater reliability underestimate the magnitude of the validity. The implications of these findings for future efforts to estimate criterion reliability and predictor validity are discussed.     

The Guise of the Guise of the Bad

It is undeniable that human agents sometimes act badly, and it seems that they sometimes pursue bad things simply because they are bad. This latter phenomenon has often been taken to provide counterexamples to views according to which we always act under the guise of the good (GG). This paper identifies several distinct arguments in favour of the possibility that one can act under the guise of the bad. GG seems to face more serious difficulties when trying to answer three different, but related, arguments for the possibility of acting under the guise of the bad. The main strategies available to answer these objections end up either undermining the motivation for GG or failing to do full justice to the nature of perverse motivation. However, these difficulties turn out to be generated by focusing on a particular version of GG, what I call the “content version”. But we have independent reasons to prefer a different version of GG; namely, the “attitude version”. The attitude version allows for a much richer understanding of the possibility of acting on what we conceive to be bad. Drawing on an analogy with theoretical akrasia and theoretical perversion, I try to show how the attitude version can provide a compelling account of perverse actions.     

“I Believe People Need to Know Us in Order to Integrate Us”: Immigrant Women’s Cultural Attitudes and Needs

The integration of immigrant women is crucial for achieving coexistence and social cohesion in diverse societies. In particular, the analysis of the role of migrant women has a recent but strong tradition within sociology literature. From a gender perspective, this paper analyzes how immigrant women conceive of themselves in a process of sociocultural integration. Methodologically, this is a qualitative investigation based on in-depth semi-structured interviews of 60 immigrant women. The interviews were conducted in Galicia (Spain) and include diverse nationalities from Latin America, Europe, Africa, and Asia. Following an intersectional approach, the analysis of their responses showed that the value they placed on themselves, their cultures, and/or their languages of origin in a receiving society varied depending on the co-articulation of variables such as class, race, and formal level of education. For example, being the level of education the categorizing variable, participants from the higher-educated (HE) group stressed the importance of bringing attention to their cultural particularities in order to favor immigrants’ integration, whereas those from the lower-educated (LE) group did not see any relationship between the preservation of their cultural background and the process of integration.     

Development of rule-based eye-hand-decoupling in children and adolescents

In the present study, we characterize how the ability to decouple guiding visual information from a motor action emerges during childhood and adolescence. Sixty-two participants (age range 8–15 yrs.) completed two eye-hand coordination tasks. In a direct interaction task, vision and motor action were in alignment, and participants slid their finger along a vertical touch screen to move a cursor from a central target to one of four peripheral targets. In an eye-hand-decoupled task, eye and hand movements were made in different planes and cursor feedback was 180° reversed. We analyzed whether movement planning, timing and trajectory variables differed across age in both task conditions. There were no significant relationships between age and any movement planning, timing, or execution variables in the direct interaction task. In contrast, in the eye-hand-decoupled task, we found a relationship between age and several movement planning and timing variables. In adolescents (13–15 yrs.), movement planning and timing was significantly shorter than that of young children (8–10 yrs.). Eye-hand-decoupled maturation emerged mainly during late childhood (11–12 yrs.). Notably, we detected performance differences between young children and adolescents exclusively during the eye-hand decoupling task which required the integration of rule-based cognitive information into the motor action. Differences were not observed during the direct interaction task. Our results quantify an important milestone for eye-hand-decoupling development in late childhood, leading to improved rule-based motor performance in early adolescence. This eye-hand-decoupling development may be due to frontal lobe development linked to rule-based behavior and the strengthening of fronto-parietal networks.     

Eye movements disrupt episodic future thinking

Remembering the past and imagining the future both rely on complex mental imagery. We considered the possibility that constructing a future scene might tap a component of mental imagery that is not as critical for remembering past scenes. Whereas visual imagery plays an important role in remembering the past, we predicted that spatial imagery plays a crucial role in imagining the future. For the purpose of teasing apart the different components underpinning scene construction in the two experiences of recalling episodic memories and shaping novel future events, we used a paradigm that might selectively affect one of these components (i.e., the spatial). Participants performed concurrent eye movements while remembering the past and imagining the future. These concurrent eye movements selectively interfere with spatial imagery, while sparing visual imagery. Eye movements prevented participants from imagining complex and detailed future scenes, but had no comparable effect on the recollection of past scenes. Similarities between remembering the past and imagining the future are coupled with some differences. The present findings uncover another fundamental divergence between the two processes.     

Event centrality of positive and negative autobiographical memories to identity and life story across cultures

The aim of this study was to investigate whether cultural differences exist in event centrality, emotional distress and well-being in a total of 565 adults above age 40 from Mexico, Greenland, China and Denmark. Participants completed questionnaires to determine their level of post-traumatic stress disorder and depression symptoms, and of life satisfaction. They also completed event centrality scales for their most positive and most negative life events. Across cultures, participants rated positive events as more central to their identity and life stories, compared with negative events. Furthermore, participants with higher levels of emotional distress rated negative events as more central to their identity and life story, compared with participants with lower scores. However, a converse pattern was not found for positive events. Finally, participants with higher scores of life satisfaction tended to rate positive events as more central and negative events as less central to their identity and life story, compared with participants with lower scores. It is concluded that across cultures, positive events are considered more central to identity and life story than negative events and that event centrality ratings tend to be affected in similar ways by higher versus lower levels of emotional distress or well-being.     

Just lying there,remembering: Improving recall of prose in amnesic patients with mild cognitive impairment by minimising interference

The hallmark of amnesia is poor explicit long‐term memory along with normal short‐term memory. It is often stated that information encountered by amnesic patients is forgotten within 1 minute of presentation. However, previous work has not distinguished between forgetting as a function of time versus the interfering material occupying that time. We show that there is a marked benefit of reduced interference in amnesic patients with mild cognitive impairment (MCI), a condition that is characterised by anterograde amnesia in the absence of other neuropsychological deficits and carries an increased risk for Alzheimer's disease. The result suggests that long‐term memory is encoded in these patients to a greater extent than had been realised but that their memory is highly vulnerable to interference.
