A Trial of Psychopharmacologic Measurement with Projective Techniques

An interactive computer program was developed in the BASIC language to present the performance and inquiry phases of the Rorschach Inkblot Test. As the subjects handled the traditional cards they entered their perceptions into the computer database, guided by instructions presented on the computer display. No assumptions were made about the percepts, but the Klopfer scoring questions were asked directly by the computer during the inquiry. The program scored the test as the subject answered the scoring questions on the keyboard. Thirty subjects were assessed using a test-retest design. One subgroup was tested first by a psychologist, and the other was tested first by the computer. The determinants of the psychologist and computer testing situations were found to be correlated and overall not significantly different except in location and time scores where the media differed.     

Do Mindsets Shape Students’ Well-Being and Performance?

“Mindsets (or implicit theories) are people’s lay beliefs about the nature of human attributes, such as intelligence or personality”. Individuals with a fixed mindset believe that intelligence is an unchangeable trait, whereas those with a growth mindset think of it as a malleable quality that can be increased and developed. This study explored the relationships among growth mindset, wellbeing, and performance in a sample of 1,240 students from a multi-campus private university located in 18 states across Mexico. Our results indicated that individuals who scored high in growth (vs. fixed) mindset showed increased levels of wellbeing and also performed better in school. Furthermore, we found that wellbeing mediated the relationship between growth mindset and performance and that the effect of growth mindset on grades was higher among younger students. These findings have interesting implications for psychology and education.     

About the artist: Craig antrim

Our cover artist, Alok Hsu Kwang-Han, has a truly adventurous spirit that has led him to motorbike through Tibet, to study and live in India, returning twenty or more times, and to travel the world with his brushes, paper, and an open heart. Last year, he gave a workshop to benefit Psychological Perspectives, which was very well attended. His art is a unique blending of several traditions that evolved over decades. In his words     

Persistent impairments in hippocampal function following a brief series of photoperiod shifts in rats

The impact of an acute circadian disruption on learning and memory in male and female rats was examined. Circadian disruption was elicited using a brief series of photoperiod shifts. Previous research using male rats showed that acute circadian disruption during acquisition of a spatial navigation task impaired long-term retention and that chronic circadian disruption impaired acquisition of the same task. However, the long-term effects of acute circadian disruption following circadian re-entrainment and whether sex differences in response to circadian disruption exist are still unknown. For the present study, rats were trained on the standard, spatial version of the Morris water task (MWT) and a visual discrimination task developed for the eight-arm radial maze. After reaching asymptotic performance, behavioural training was terminated and the experimental group experienced a series of photoperiod shifts followed by circadian re-entrainment. Following circadian re-entrainment, the subjects were given retention tests on the MWT and visual discrimination task. Following retention testing, an extra-dimensional shift using the eight-arm radial maze was also performed. An acute episode of circadian disruption elicited via photoperiod shifts negatively impacted retention of spatial memory in male and female rats. Retention of the visual discrimination task and the ability to detect extra-dimensional shifts were not impaired. The observed impairments on the MWT indicate that hippocampal representations are susceptible to a small number of photoperiod shifts even if the association is acquired prior to rhythm manipulation and retention is assessed following rhythm stabilization. Effects were limited to a hippocampus-dependent task, indicating that impairments are specific, not global.
