Regression II. Development through regression

As shown in our previous paper (‘Regression I. Experimental approaches to regression’, JAP, 65, 2, 345-65), the common mechanism of regression can be described as reversible dedifferentiation, which is understood as a relative increase of the proportion of low-differentiated (older) systems in actualized experience. Experimental data show that regression following disease (chronic tension headache) is followed by adaptation and an increase in system differentiation in that experience domain which contains systems responsible for that adaptation. The results of mathematical modelling support the idea that reversible dedifferentiation can be one of the mechanisms for increasing the effectiveness of adaptation through learning. Reversible dedifferentiation, which is phenomenologically described as regression, is a general mechanism for restructuring the organism-environment interactions in situations where behaviours that were effective in the past become ineffective. Reversible dedifferentiation has evolved as a component of adaptation when new behaviours are formed and large-scale modifications in the existing behaviours are required in the face of changes in the external and/or internal environment. Thus, the authors believe that this article provides evidence for Jung’s view that regression is not only a ‘return’ to past forms of thinking, affects and behaviour, but that regressive processes provide a significant impetus for psychological growth and development.     

Repeatability of mae-geri-keage in traditional karate: a three-dimensional analysis with black-belt karateka

In karate, performance also depends on a correct body shape, and the repeatability of standardized movements conditions the effectiveness of techniques. The execution of mae-geri-keage (frontal snap kick) was studied in 13 karateka (1st-5th dan). The 3D trajectories of 13 body landmarks were analyzed by an optoelectronic instrument while each karateka performed 10 repetitions of the movement. For each karateka and repetition, the standard deviations of the spatial coordinates x, y, z for each landmark were computed. A total standard deviation of the single participant was also calculated. Two experienced karateka performed with the best repeatability (smaller standard deviation) while executing the studied kick. Generally, the best repeatability was observed in the horizontal plane. The lower variability was observed in hips and head. Ankle and knee of the dominant limb had the worse. The method could detect athletes particularly gifted for the discipline. Moreover, it could help in the identification of those parts of body that do not repeat the movement with the desired precision.     

Cultural variation in correspondence bias: the critical role of attitude diagnosticity of socially constrained behavior

Upon observing another's socially constrained behavior, people often ascribe to the person an attitude that corresponds to the behavior (called the correspondence bias [CB]). The authors found that when a socially constrained behavior is still diagnostic of the actor's attitude, both Americans and Japanese show an equally strong CB. A major cultural difference occurred when the behavior was minimally diagnostic. Demonstrating their persistent bias toward dispositional attribution, Americans showed a strong CB. But Japanese did not show any CB (Study 1). Furthermore, a mediational analysis revealed that this cross-cultural difference was due in part to the nature of explicit inferences generated online during attitudinal judgment (Study 2). Implications for the cultural grounding of social perception are discussed.     

Exposure with response prevention versus habit reversal in Tourettes's syndrome: a controlled study

The intentional nature of tics provides the opportunity to apply behavioural interventions aimed at tic reduction through interruption of stimulus-response sequences. The aim of this study has been to evaluate the effect of exposure and response prevention (ER) versus habit reversal (HR) in 43 Tourette's syndrome (TS) patients. The three outcome measures were: the Yale Global Tic Severity Scale (YGTSS), 15-min tic frequency registrations monitored at the institute and 15-min home tic frequency registrations. Both treatment conditions resulted in statistically significant improvements on all outcome measures (p < 0.001). No significant differences were found between the treatment conditions on any of the outcome measures, although there was a tendency in favour of ER on the YGTSS (p = 0.05). These results suggest that, at least in the short term, TS tic symptoms can be treated effectively with both types of treatment.     

The effect of prolonged viewing on the recognition of global and local levels of hierarchically constructed patterns

Two experiments were carried out to examine delays in the recognition of test patterns after prolonged (25 s) viewing of an adaptation pattern which was composed of either the same or different local components and global structures. In the case of geometric patterns that contained a few relatively large elements, there were significant delays of about 70 ms in the global decision task when the test and adaptation stimuli (TS and AS) were of the same pattern, or when they had the same structure but different components. In contrast, in the case of geometric patterns that were composed of many relatively small elements, such a figural relation between the AS and the TS did not affect the recognition speed of the TSs either in the global or in the local decision task. These results suggest that prolonged viewing reduces the efficiency of global processing and that such a disruptive effect occurs depending upon the number and the relative size of the elements that make up the whole pattern.     

Striving for excellence: A multi-action plan intervention model for Shooters

ObjectivesA multi-action plan (MAP) intervention model has been applied to the Italian shooting team in preparation for the London 2012 Olympics to help athletes improve, stabilise, and optimise their performances during practice and competition.DesignA longitudinal design was adopted to assess the intervention effects over two years.MethodsFifteen participants, two female and three male carbine shooters, and five female and five male pistol shooters, took part in the study. First, shooters were requested to accurately and extensively describe their usually optimal sequence of actions for the execution of a single shot from start to follow-through. Second, shooters were asked to identify a small number of the most important core components (three or four) deemed fundamental to optimal performance. Third, performers were engaged in several shooting sessions and asked to assess themselves by rating the quality of each core component. Finally, the most influential core components were further assessed under conditions of increased distress and simulated competition.ResultsCore component ratings were linked to shooting scores classified as optimal or suboptimal. The probability levels of optimal/suboptimal performance associated with the core component ratings were derived using logistical ordinal regression analysis. The full links among core component scores and the full range of shooting scores were also examined through path analysis.ConclusionsFindings highlighted the benefits of using the MAP intervention model in the preparation of elite level shooters.     

Cultural grounding of regret: regret in self and interpersonal contexts

The purpose of this study was to explore cultural similarities and differences in regret, focusing on distinctions between interpersonal and self-situations, and between action and inaction regrets. Japanese and American undergraduates were asked to describe regrets experienced in interpersonal and self-situations. We found that both situational and cultural contexts influenced the likelihood of regretting inactions over actions. Participants were more likely to recall inaction regrets in self-situations than in interpersonal situations, and that the likelihood of recalling inaction regrets was more pronounced for Americans than for Japanese. Furthermore, we examined the intensity of the regret. Whereas American students experienced regret as intense as that of Japanese students in self-situations, Japanese students experienced regret more strongly than American students in interpersonal situations. Detailed content analysis also showed that individuals experienced regret in ways consistent with cultural values. The situational and cultural grounding of regret is discussed.     

You were always on my mind: The importance of “significant others” in the attenuation of retrieval‐induced forgetting in Japan

Research on memory has demonstrated that remembering material can cause forgetting of related information, which is known as retrieval‐induced forgetting (RIF). Macrae and Roseveare identified “self” as one of the boundary conditions of this effect in the Western cultural context, showing that RIF was eliminated when material was encoded to be related to the self (known as self‐referential effect), but not to significant others. In this study, we predicted and found that significant others could be another boundary condition in Japanese cultural contexts in which self and agency are more interdependent or conjoint; RIF was observed neither under best‐friend‐related encoding nor under family‐related encoding in Japan. The effect of significant others is found uniquely in Japanese cultural contexts, suggesting that the cultural model of self has significant power in the spontaneous system of memory.     

Real Objects Can Impede Conditional Reasoning but Augmented Objects Do Not

In this study, Knauff and Johnson‐Laird's (2002) visual impedance hypothesis (i.e., mental representations with irrelevant visual detail can impede reasoning) is applied to the domain of external representations and diagrammatic reasoning. We show that the use of real objects and augmented real (AR) objects can control human interpretation and reasoning about conditionals. As participants made inferences (e.g., an invalid one from "if P then Q" to "P"), they also moved objects corresponding to premises. Participants who moved real objects made more invalid inferences than those who moved AR objects and those who did not manipulate objects (there was no significant difference between the last two groups). Our results showed that real objects impeded conditional reasoning, but AR objects did not. These findings are explained by the fact that real objects may over‐specify a single state that exists, while AR objects suggest multiple possibilities.     

Culture and the physical environment. Holistic versus analytic perceptual affordances

Westerners' perceptions tend to focus on salient foreground objects, whereas Asians are more inclined to focus on contexts. We hypothesized that such culturally specific patterns of attention may be afforded by the perceptual environment of each culture. In order to test this hypothesis, we randomly sampled pictures of scenes from small, medium, and large cities in Japan and the United States. Using both subjective and objective measures, Study 1 demonstrated that Japanese scenes were more ambiguous and contained more elements than American scenes. Japanese scenes thus may encourage perception of the context more than American scenes. In Study 2, pictures of locations in cities were presented as primes, and participants' subsequent patterns of attention were measured. Both Japanese and American participants primed with Japanese scenes attended more to contextual information than did those primed with American scenes. These results provide evidence that culturally characteristic environments may afford distinctive patterns of perception.
