Young children share the spoils after collaboration

Egalitarian behavior is considered to be a species-typical component of human cooperation. Human adults tend to share resources equally, even if they have the opportunity to keep a larger portion for themselves. Recent experiments have suggested that this tendency emerges fairly late in human ontogeny, not before 6 or 7 years of age. Here we show that 3-year-old children share mostly equally with a peer after they have worked together actively to obtain rewards in a collaboration task, even when those rewards could easily be monopolized. These findings contrast with previous findings from a similar experiment with chimpanzees, who tended to monopolize resources whenever they could. The potentially species-unique tendency of humans to share equally emerges early in ontogeny, perhaps originating in collaborative interactions among peers.     

Efficacy of cognitive training programs based on new software technologies in patients with Alzheimer-type dementia

The study aims to assess the efficacy of the Big Brain Academy (BBA), a computerized cognitive training program (CT) based on video games, compared to the Integrated Psychostimulation Program (IPP), a classical CT tool for patients with Alzheimer's disease (AD). A total of 45 patients with AD at the mild stage were randomly assigned to three experimental conditions. Two treatment groups were established, in which patients received either a stimulation program with BBA (EABB) or a traditional stimulation program (EAPI), based on paper-and-pencil tasks, for twelve weeks. A third group, the control group (EANT), did not receive any treatment during this period. The differential effectiveness of the programs was evaluated through pre-post design, considering neuropsychological, behavioral, and functional standard measures as outcome variables. The EABB group showed significantly slower rates of cognitive decline compared to the EAPI and EANT groups. Furthermore, the EABB group reported significantly greater decrease in depressive symptoms in comparison with the EAPI and EANT groups. The BBA program was more effective than IPP to reduce cognitive decline and depressive symptoms in patients with AD.     

Incorporating a Psychological Counselor in a Cancer Risk Assessment Program: Necessity, Acceptability, and Potential Roles

Evidence suggests that cancer risk assessment may be associated with increased psychological distress. This exploratory study assessed the necessity and acceptability of incorporating psychological counseling into routine clinic procedures at a cancer risk program. Following a visit to a university-based cancer risk clinic, patients (N = 102) completed an anonymous self-report instrument. Participants reported experiencing current stress and anxiety (41%), depression (29%), and suicidal ideation (2%). Patients with a history of cancer were more likely to be experiencing current emotional difficulties. Sixty-nine percent of the participants found the visit with the psychological counselor to be helpful, while 41% of the participants reported interest in follow-up psychological services. Interest in receiving future psychological services was positively correlated with levels of anxiety, depression, and cancer worry. This pilot study demonstrates the acceptability and potential role for psychological counselors in increasing adjustment in high-risk patients undergoing genetic counseling for inherited cancers.

Evaluating psychological injury in motor vehicle accidents (MVA): development and validation of a protocol for detecting pretense

In order to assess the feigning ability of the psychological injury in a motor vehicle accident (MVA), a total of 105 subjects, which never had suffered a serious MVA and lay in psychopathology, responded to the MMPI-2 in line with the standard instructions. Thereafter, subjects were instructed to feign moral damage generated by a MVA prior to being evaluated using a clinical-forensic interview a week later, and responding to the MMPI-2 another week later. The results show that 60.9% of the subjects were able to effectively feign moral damage on the MMPI-2, and 3.8% in the forensic clinical interview. The analysis of the instruments and procedures for the validation of subject responses i.e., the original validity control scales of the MMPI-2 and the analysis of feigning strategies in the forensic clinical interview, revealed no efficacy in feigning detection. Nevertheless, collectively, all the control measures and procedures were effective for the detection of feigning. Therefore, a protocol for the detection of feigning of moral damage has been proposed.     

Frames of Reference in Self-Reports of Health,Well-Being,Fatigue, and Pain: a Qualitative Examination

Self-reports in survey research can be affected by internal comparison standards, or Frames of Reference (FoRs), that people apply when making their ratings. The goal of this study was to determine which FoRs people naturally use when rating their health, subjective well-being, fatigue, and pain. We further examined whether FoRs varied by content domain and age group. One hundred adults from a community sample of the US general population participated in individual semi-structured qualitative interviews. Participants provided self-report ratings on two of the four content domains and were then systematically queried about FoRs. Interview responses were summarized and coded into broad FoR categories. Four broad FoR categories emerged: References to (1) Other People, (2) an Earlier Time in Life, (3) an Important Event in the Past, and (4) a Hypothetical Situation. FoRs were reported in the majority (80.5%) of responses and multiple FoRs were reported in 34% of responses. The reporting of FoRs was evident for all domains, but was more prevalent for well-being compared to pain. References to a Hypothetical Situation were only mentioned in the well-being and health domains. For health, references to Other People were more frequently reported at older compared to younger ages. Our results extend prior work by demonstrating that participants’ reporting of FoRs is evident in ratings of various content domains. They further suggest that a limited number of FoRs are used and that their identification holds promise for understanding and controlling systematic group differences in FoRs.     

Why does visual working memory ability improve with age: More objects,more feature detail,or both? A registered report

We investigated how visual working memory (WM) develops with age across the early elementary school period (6–7 years), early adolescence (11–13 years), and early adulthood (18–25 years). The work focuses on changes in two parameters: the number of objects retained at least in part, and the amount of feature-detail remembered for such objects. Some evidence suggests that, while infants can remember up to three objects, much like adults, young children only remember around two objects. This curious, nonmonotonic trajectory might be explained by differences in the level of feature-detail required for successful performance in infant versus child/adult memory paradigms. Here, we examined if changes in one of two parameters (the number of objects, and the amount of detail retained for each object) or both of them together can explain the development of visual WM ability as children grow older. To test it, we varied the amount of feature-detail participants need to retain. In the baseline condition, participants saw an array of objects and simply were to indicate whether an object was present in a probed location or not. This phase begun with a titration procedure to adjust each individual's array size to yield about 80% correct. In other conditions, we tested memory of not only location but also additional features of the objects (color, and sometimes also orientation). Our results suggest that capacity growth across ages is expressed by both improved location-memory (whether there was an object in a location) and feature completeness of object representations.
