Auditory and visual differences in time perception? An investigation from a developmental perspective with neuropsychological tests

Adults and children (5- and 8-year-olds) performed a temporal bisection task with either auditory or visual signals and either a short (0.5-1.0s) or long (4.0-8.0s) duration range. Their working memory and attentional capacities were assessed by a series of neuropsychological tests administered in both the auditory and visual modalities. Results showed an age-related improvement in the ability to discriminate time regardless of the sensory modality and duration. However, this improvement was seen to occur more quickly for auditory signals than for visual signals and for short durations rather than for long durations. The younger children exhibited the poorest ability to discriminate time for long durations presented in the visual modality. Statistical analyses of the neuropsychological scores revealed that an increase in working memory and attentional capacities in the visuospatial modality was the best predictor of age-related changes in temporal bisection performance for both visual and auditory stimuli. In addition, the poorer time sensitivity for visual stimuli than for auditory stimuli, especially in the younger children, was explained by the fact that the temporal processing of visual stimuli requires more executive attention than that of auditory stimuli.     

Individual differences in working memory capacity predict sleep-dependent memory consolidation

Decades of research have established that "online" cognitive processes, which operate during conscious encoding and retrieval of information, contribute substantially to individual differences in memory. Furthermore, it is widely accepted that "offline" processes during sleep also contribute to memory performance. However, the question of whether individual differences in these two types of processes are related to one another remains unanswered. We investigated whether working memory capacity (WMC), a factor believed to contribute substantially to individual differences in online processing, was related to sleep-dependent declarative memory consolidation. Consistent with previous studies, memory for word pairs reliably improved after a period of sleep, whereas performance did not improve after an equal interval of wakefulness. More important, there was a significant, positive correlation between WMC and increase in memory performance after sleep but not after a period of wakefulness. The correlation between WMC and performance during initial test was not significant, suggesting that the relationship is specific to change in memory due to sleep. This suggests a fundamental underlying ability that may distinguish individuals with high memory capacity.     

Cultural inertia: The effects of cultural change on intergroup relations and the self-concept

Throughout the world, immigration and the ensuing political reactions have become dominant social problems in the 21st century. One contributor to these problems includes the continual social change. In the United States, ethnic minority populations are growing while the White majority is becoming proportionally smaller. It is proposed that change, in and of itself, can produce intergroup tension. Here, the concept of cultural inertia is introduced as one contributor to intergroup prejudice. Cultural inertia entails a resistance to change, unless change is already occurring. Change is perceived differently across groups as a function of how well the groups already match the current dominant culture. Cultural inertia causes differential preferences for cultural change as a function of the extent to which people identify with a cultural group, their sense of esteem for a cultural group, and the perception that a culture is (or is not) already changing. Three studies manipulated participants' perception of cultural change and show that cultural change influences inter-group prejudice, group esteem, and engagement with the culture. The implications of cultural inertia for models of intercultural ideologies are discussed.     

Early detection of drug use and bullying in secondary school children by using a three-dimensional simulation program

The current study analyzes the psychometric properties of an innovative three-dimensional (3D) simulation program, entitled Mii-School (MS), designed for the early detection of drug use and bullying in Secondary School children. This computer program showed adequate reliability and construct validity. The factorial structure, as well as the explanatory weight of the different factors, is presented. In addition, the results of a parallel version in paper and pencil format are also presented and compared with those of the computerized version (i.e., MS). There was a statistically significant difference between the two formats in the total (i.e., combined) sore of risk. When drug use and bullying were separately analyzed, differences were found only with regard to drug use. The relevance of these results as well as the suitability of this type of 3D instrument for the early detection of risky behaviors in young people are discussed.     

Roles of domain knowledge and working memory capacity in components of skill in Texas Hold’Em poker

Domain knowledge is a powerful predictor of success in many complex tasks, but do general cognitive abilities also play a role? To investigate this question, we had 155 participants representing a wide range of poker experience and skill complete tests of poker knowledge, working memory capacity (WMC), and two components of skill in Texas Hold’Em poker: the ability to remember hands and the ability to evaluate hands. Not surprisingly, poker knowledge positively predicted performance in all of the Hold’Em tasks. However, WMC added significantly to the prediction, and there was no evidence for interactions between poker knowledge and WMC. That is, WMC was as important as a predictor of performance at high levels of poker knowledge as at low levels, suggesting that domain knowledge may not always enable circumvention of WMC in domain-relevant tasks.     

Use of Psychotropic Medications Among Youth in Treatment Foster Care

We describe the use of psychotropic medications among youth in treatment foster care (TFC). Data from 240 youth were coded to examine rates of medication use, including polypharmacy and an indicator of “questionable polypharmacy.” Fifty-nine percent of youth in TFC had taken a psychotropic medication within the past 2 months. Of the youth taking psychotropics, 61 % took two or more and 22 % met criteria for questionable polypharmacy. The majority of youth taking psychotropics also received psychosocial mental health services and were more likely to receive such services than youth not taking medication. Use of psychotropic medication use was not significantly related to demographic factors, maltreatment history, or custody. However, youth with more severe symptoms were more likely to be on medications and to be on multiple medications. Youth with “questionable polypharmacy” were less likely than other youth on multiple medications to have a recent visit to a psychiatrist.     

Perception and Help-Seeking Intention of Intimate Partner Violence in Later Life: An International Perspective

This study examines whether elderly Koreans recognize a scenario of intimate partner violence as such and whether they would seek help in the given situation of elder mistreatment (EM). Two cohorts of Korean elders (one immigrant and one Korea-based), each numbering 124 participants, were recruited using a quota sampling strategy. The study used a mixed method approach, employing a hypothetical scenario, and patriarchy theory informed the study. Findings revealed low perception of the vignette as EM and low help-seeking intention in both cohorts. Among the immigrant cohort, intention to seek help was greater among respondents who were female, demonstrated lower adherence to traditional values, and perceived the vignette as EM. Among the Korea-based cohort, the only significant factor was recognition of the scenario as EM. Development of culturally competent and geographically specific practice and intervention is urgently needed, particularly among elders who have greater adherence to traditional cultural values.     

Beliefs About Faith and Work: Development and Validation of Honoring God and Prosperity Gospel Scales

Disputes over the connection between beliefs and behaviors, coupled with the relative paucity of survey measures of specific theological beliefs related to work and its association with financial success, motivated the development of two beliefs scales: beliefs about work as a means to honor God and beliefs about God promising prosperity for believers. Analyses demonstrated these two scales to be distinct from one another and reliable. Using a national sample of over 1,000 working adults, we assessed the relationship of the specific belief scales to Lynn et al.’s (J Bus Ethics 85(2):227–241, 2009) faith at work scale, Mirels and Garrett’s (J Consul Clin Psychol 36(1):40–44, 1971) Protestant Work Ethic scale, two personality scales (Conscientiousness and Neuroticism), entrepreneurial behavior, helping behavior, and religious tradition. Results indicate convergent and divergent validity and demonstrate the potential utility of these beliefs scales for predicting work-related attitudes and practices.     

Dissertation experiences of doctoral graduates from professional psychology programs

Worldwide, dissertation experiences are acknowledged to be challenging endeavors for students and the faculty members who advise them, and dissertation completion continues to be a concern when seeking to improve overall doctoral graduation rates. Although a number of factors have been associated with completion rates across disciplines, further research is needed within professional psychology graduate programs to understand overall student dissertation experiences. In this USA-based investigation, a mixed-method design was used to examine the experiences of 25 professional psychology doctoral graduates’ dissertation experiences, 12 of which were self-identified as positive and 13 as negative. Participants with positive experiences typically had supportive relationships with their dissertation chairs and committee members, which enhanced their research confidence and professional development. Participants with negative dissertation experiences typically had difficult relationships with dissertation chairs and committee members, which was associated with immediate and long-lasting negative consequences for participants’ professional growth and emotional well-being. The advisory working alliance was stronger for graduates with positive than negative experiences, although research attitudes and self-efficacy beliefs were not different between the two groups.
