Journeys With People Who Have Dementia: Connecting and Finding Meaning in the Journey

This article begins with a reflective journey with one person who was diagnosed with early onset dementia. It then turns to reflect on the subsequent journey of research with other people who have dementia and where they find meaning in life, through the process of spiritual reminiscence. The article views dementia through a theological lens that sees those who have dementia as people made in God’s image and the implications this has for the lives of those living with dementia and those who care for them. One of the important findings from research conducted in the small group process was that meaning was almost synonymous with relationship and connectedness for participants, just as it is for people who don’t have dementia.     

Endogenous attention modulates early selective attention in psychopathy: An ERP investigation

Psychopathic individuals are prone to act on urges without adequate consideration of future consequences or the rights of other individuals. One interpretation of this behavior is that it reflects abnormal selective attention (i.e., a failure to process information that is incongruent with their primary focus of attention; Hiatt, Schmitt, & Newman, Neuropsychology, 18, 50-59, 2004). Unfortunately, it is unclear whether this selective attention abnormality reflects top-down endogenous influences, such as the strength or specificity of attention focus (i.e., top-down set) apart from other, more exogenous (bottom-up), effects on attention. To explore this question, we used an early visual event-related potential (N2pc) in combination with a modified visual search task designed to assess the effect of early endogenous (i.e., top-down) attention on the processing of set-congruent information. The task was administered to a sample of 70 incarcerated adult males, who were assigned to high, intermediate, and low psychopathy groups using Hare’s Psychopathy Checklist-Revised (Hare, 2003). Based on the assumption that their failure to process set-incongruent information reflects the exaggerated effects of endogenous attention, we predicted that participants with high psychopathy scores would show an exaggerated N2pc response to set-congruent information. The results supported the hypothesis and provide novel electrophysiological evidence that psychopathy is associated with exaggerated endogenous attention effects during early stages of processing. Further research is needed to examine the implications of this finding for the well-established failure of psychopathic individuals to process set-incongruent information and inhibit inappropriate responses.     

Children view own-age faces qualitatively differently to other-age faces

Like most own-group biases in face recognition, the own-age bias (OAB) is thought to be based either on perceptual expertise or socio-cognitive motivational mechanisms [Wolff, N., Kemter, K., Schweinberger, S. R., &; Wiese, H. (2013). What drives social in-group biases in face recognition memory? ERP evidence from the own-gender bias. Social Cognitive and Affective Neuroscience. doi:10.1093/scan/nst024]. The present study employed a recognition paradigm with eye-tracking in order to assess whether participants actively viewed faces of their own-age differently to that of other-age faces. The results indicated a significant OAB (superior recognition for own-age relative to other-age faces), provided that they were upright, indicative of expertise being employed for the recognition of own-age faces. However, the eye-tracking results indicate that viewing other-age faces was qualitatively different to the viewing of own-age faces, with more nose fixations for other-age faces. These results are interpreted as supporting the socio-cognitive model of the OAB.     

The effects of co‐occurring ADHD symptoms on electrophysiological correlates of cognitive control in young people with Tourette syndrome

Efficient cognitive control is implicated in tic control in young people with Tourette syndrome (TS). Attention‐deficit/hyperactivity disorder (ADHD) frequently co‐occurs with TS and is associated with impaired cognitive control. Young people with TS and ADHD (TS+ADHD) show poorer cognitive control performance than those with TS, but how co‐occurring ADHD affects underlying neural activity is unknown. We investigated this issue by examining behavioural and event‐related potential (ERP) correlates of cognitive control in young people with these conditions. Participants aged 9–17 with TS (n = 17), TS+ADHD (n = 17), ADHD (n = 11), and unaffected controls (n = 20) performed a visual Go/Nogo task during electroencephalography (EEG) recording. Behavioural performance measures (D‐prime, RT, reaction time variability, post‐error slowing) and ERP measures (N2, P3, error‐related negativity (ERN), error positivity (Pe)) were analysed in a 2 (TS‐yes, TS‐no) × 2 (ADHD‐yes, ADHD‐no) factorial analysis to investigate the effects of TS, ADHD, and their interaction. The results of these analyses showed that ADHD was associated with poorer performance and reduced amplitude of all ERPs, reflecting widespread cognitive control impairments. Tourette syndrome was associated with slowed RTs, which might reflect a compensatory slowing of motor output to facilitate tic control. There was no interaction between the TS and ADHD factors for any behavioural or ERP measure, indicating the impairing effects of ADHD on behaviour and electrophysiological markers of cognitive control were present in TS+ADHD and that RT slowing associated with TS was unaffected by co‐occurring ADHD symptoms.     

Health and Aging: A Perspective from the Far East

Singapore is an urban, highly industrialized country in South East Asia. By 2030, one-fifth of the population is projected to be composed of citizens aged above 65 years. Research on aging has largely focused on the effects of deteriorating physical ability on daily functioning capabilities (Iwarsson & Isacsson, 1997; Warr, 1995). More recently, the role of self-perceived usefulness, competence and control on well-being in the elderly have been investigated (Heberlein, Licht & Licht, 1999; Ranzjin, Keeves, Luszcz, & Feather, 1998). In other fields, activity and involvement have been identified as effective coping devices (Nair, 1989; Shalit, 1988). The present study compared the conceptual understanding of the esteem and well-being of the elderly on the dimensions of activity, involvement, and control, as viewed by an undergraduate sample (n = 60) and a cross-section of seniors (n = 71). Three separate factor analyses reflected interesting variations in the conceptual frameworks.     

Two‐year‐olds’ naîve predictions for horizontal trajectories

Hood recently reported that preschool children overgeneralized the prediction that falling objects travel in a straight line in spite of extensive counter‐evidence that the object had been deviated to a non‐aligned box by a tube. This behaviour was interpreted as a na?^ve theory of gravity resulting from an overgeneralization derived from experience of falling objects. The current study set out to test whether there was also a significant tendency for 2‐year‐olds to predict that objects travel in a straight line in the horizontal plane. This was achieved by comparing search for an invisibly displaced object moving either vertically or horizontally. The findings confirmed a gravity bias for falling events but did not reveal a similar tendency in the horizontal condition. In the horizontal task, children were as likely to search at an incorrect non‐aligned box as an aligned incorrect box. This supports the interpretation of a na?^ve gravity bias present from at least 2 years of age.     

Sikolohiyang Pilipino (Filipino psychology): A legacy of Virgilio G. Enriquez

Sikolohiyang Pilipino (Filipino psychology) refers to the psychology born out of the experience, thought and orientation of the Filipinos, based on the full use of Filipino culture and language. The approach is one of "indigenization from within" whereby the theoretical framework and methodology emerge from the experiences of the people from the indigenous culture. It is based on assessing historical and socio-cultural realities, understanding the local language, unraveling Filipino characteristics, and explaining them through the eyes of the native Filipino. Among the outcomes are: a body of knowledge including indigenous concepts, development of indigenous research methods and indigenous personality testing, new directions in teaching psychology, and an active participation in organisations among Filipino psychologists and social scientists, both in the Philippines and overseas.
