Diminished joint coordination with aging leads to more variable hand paths

Differences in joint coordination between arms and due to aging were studied in healthy young and older adults reaching to either a fixed, central target or to the same target when it could unexpectedly change location after reach initiation. Joint coordination was investigated by artificially removing the covariation of each joint’s motions with other joints’ motions. Uncontrolled manifold analysis was used to partition joint configuration variance into variance reflecting motor abundance (V_UCM) and variance causing hand path variability (V_ORT). The extent to which V_ORT, related to the consistency of the hand path, increased after removing a joint’s covariation indicated the strength of its coordination with other joints. Young adults exhibited stronger indices of joint coordination, evidenced by a larger increase in V_ORT after removing joint covariation than for older adults. This effect was more striking for the dominant right compared to the left arm for young adults, but not for older adults, especially with target uncertainty. The results indicate that interjoint coordination in young adults leads to less hand path variability compared to older adults.     

Changes in Children's Pretend Play Over Two Decades

There is growing recognition that children have less time to engage in play, and, concurrently, recent evidence suggests a decrease in divergent thinking ability in young children. This study investigated changes in pretend play ability during a 23-year period. The same standardized measure of pretend play, the Affect in Play Scale (APS; Russ, 1993 Russ , S. W. ( 1993 ). Affect in creativity: The role of affect and play in the creative process . Hillsdale , NJ : Lawrence Erlbaum Associates . [Google Scholar]; 2004 Russ , S. W. ( 2004 ). Play in child development and psychotherapy: Toward empirically supported practice . Mahwah , NJ : Lawrence Erlbaum Associates Publishers . [Google Scholar]), was the measure of pretend play in all studies. This puppet play task is videotaped and scored from the tapes. Fourteen studies of children from 6 to 10 years of age in school-based samples from 1985–2008 were included in the analyses. A cross-temporal meta-analysis examined correlations between weighted mean scores and year of data collection. Main findings were that imagination in play and comfort with play significantly increased over time. There was no evidence of change in organization of the story or in overall expression of affect in play. When one outlier was removed, there was a significant decrease in negative affect expression in play. Even though children have less time to play, cognitive processes that occur in play are continuing to develop. Whether these pretend abilities are being transferred to creative production is a key question for future investigation.     

Reports from the Front: The Effects of Hurricane Katrina on Mental Health Professionals in New Orleans

Hurricane Katrina created an unprecedented mental health crisis in New Orleans. Once they could return to work, local mental health professionals attempted to treat survivors of the storm while dealing with the storm's impact on themselves. Those working in public settings were offered in-service training and supervision. But clinicians in private practice often found themselves bearing the brunt of posttraumatic uncertainty alone. The current paper includes four experiential reports from area clinicians describing their early struggles to maintain a sense of continuity in their ongoing clinical work, only to realize how much of the personal is also professional in the aftermath of a disaster of this magnitude, and how personal and professional inevitably inform one another when clinicians and patients survived similar dangers and losses. The introduction locates these four papers in the larger context of post-Katrina New Orleans and a program that was specifically tailored to meet the needs of local clinicians. This program demonstrated the ways in which psychoanalytic ideas can be used to give meaning to a traumatized mental health community's profound disorientation.     

Psychoanalytic Healing,Love, Life,and Death: Commentary on Paper by Sheldon Bach

In his seminal clinical writings on psychoanalysis, Sheldon Bach transcends the limiting confines of individual and parochial schools of psychoanalysis. Both in “On Digital Consciousness” and in his 2006 Getting From There to Here: Analytic Love, Analytic Process, we see a strong relational dimension in Bach's work (see also Bach 1985 Bach, S. 1985. Narcissistic states and the therapeutic process, Northvale, NJ: Aronson.  [Google Scholar] and 1994), though he comes from firmly within the psychoanalytic mainstream. Bach's writings speak to clinicians across schools of thought, are clinically near to experience and are often moving. While he makes occasional mention of his contemporaries, Bach is grounded in more traditional references and only hints at his intellectual connection to relational and intersubjective theorists. One purpose of this commentary is to reflect on Bach's contribution to contemporary psychoanalysis and to draw out the connections between his work and the work of those within the broader relational and intersubjective community of psychoanalysis.     

Reading your own lips: Common-coding theory and visual speech perception

Common-coding theory posits that (1) perceiving an action activates the same representations of motor plans that are activated by actually performing that action, and (2) because of individual differences in the ways that actions are performed, observing recordings of one’s own previous behavior activates motor plans to an even greater degree than does observing someone else’s behavior. We hypothesized that if observing oneself activates motor plans to a greater degree than does observing others, and if these activated plans contribute to perception, then people should be able to lipread silent video clips of their own previous utterances more accurately than they can lipread video clips of other talkers. As predicted, two groups of participants were able to lipread video clips of themselves, recorded more than two weeks earlier, significantly more accurately than video clips of others. These results suggest that visual input activates speech motor activity that links to word representations in the mental lexicon.     

Testing the hypothesized effect of dysgenic fertility on intelligence with existing reaction time data: A comment on Woodley,te Nijenhuis,and Murphy (2013)

Dysgenic fertility has supposedly resulted in a decline in general intelligence (g) over time. In light of evidence that simple visual reaction time (RT) is inversely related to IQ, Woodley et al. (2013) tested the hypothesized dysgenic effect by subjecting to a meta-regression simple visual RT data collected over 100 years in 15 studies. This analysis found that RT had significantly increased according to a linear function over this time period. Woodley et al. then used this result to estimate the rate at which g had declined over the same period. The present comment points out that there are large gaps in the distribution of RTs analyzed by Woodley et al. with respect to year tested, and that RT in males did not vary as a function of year in the 13 studies published from 1941 on. It is concluded that although existing data are consistent with the idea that g has been adversely affected by dysgenic fertility, it cannot be determined at what rate g has fallen over time.     

Regression in the Service of the Ego: A Case Study

A study was made of a 41 year old woman who was given psychological tests at the beginning of a five-year period of psychoanalytically oriented psychotherapy. From extensive material gathered from her therapist it was clear that: (a) Her pathology did not extend beyond the neurotic range; (b) she was a highly creative individual. Thus, it was of interest to note that her Rorschach contained many responses involving blatant primary process thinking. While such responses would be taken ordinarily as indicating a thinking disorder and consequently severe pathology, in this case they were seen as reflecting “regression in the service of the ego.” This led to a discussion of how this adaptive regression can be differentiated from pathological regression in psycho-diagnostic testing and to a consideration of some theoretical issues relating to primary process thinking.     

The impact of COVID-19 concerns on perceiving others' faces

Unlike most infectious diseases, COVID-19 is characterised by an absence of facial disease-signalling cues. Yet, it is still unclear whether it has influenced face perception. Understanding this may help clarify if and how our motivation toward social interactions is conditional on situational pathogen threats. The present study investigated if priming disease concerns about COVID-19 would change people's perception of neutral faces on perceived disease, social discomfort and arousal elicited by such faces; this condition was compared with other infectious/non-infectious diseases and a non-disease priming condition. One-hundred sixty-six participants recruited nationally performed the online task. When compared with the non-disease condition, participants primed for COVID-19 perceived faces as sicker and tended to view them as eliciting more social discomfort; no difference occurred in arousal. No other difference was found between conditions. These findings suggest that the pandemic context can shape how we perceive others' apparent sickness. Overall, these might reflect adaptations intertwined with the behavioural immune system's defence mechanisms.
