Interfering with the Central Executive by Means of a Random Interval Repetition Task

Four dual-task experiments are reported in which a short-term memory task is performed concurrently with a random interval repetition task, which was designed to interfere with functions normally attributed to the central executive in the working memory model of Baddeley and Hitch (1974). The task was found to interfere with supra-span serial recall and with backward memory span, but did not disrupt performance on a forward-memoryspan task. The effects were observed in dissociation with effects of articulatory suppression and matrix tapping, so that the locus of the effects of the new task is not due to the slave systems. In addition, single-task random-interval repetition performance was sampled and compared to performance in the dual-task conditions of all four experiments. Although quality of tapping performance differed between the single-task and the dual-task conditions, it was not related to recall performance. All the results are discussed with reference to the working memory model.     

Victims' Satisfaction With Compensation: Effects of Initial Disadvantage and Third Party Intervention

Two experiments examined the reactions of victims of disadvantage to compensation designed to improve their lot. In Experiment 1, subjects participated in an organizational simulation where they were disadvantaged with respect to their pay. Subsequently, a third party intervened with one of a number of strategies which varied according to whether or not the subjects received compensation and whether or not the person responsible for their disadvantage suffered. The interaction between compensation and suffering was significant on a satisfaction measure and the pattern indicated that subjects were most satisfied when the harmdoer suffered to provide compensation. This interaction was not significant on a measure of perceptions of fairness. Experiment 2 examined the possibility that the intervention of the third party in Experiment 1 may have created feelings of indebtedness. In a similar paradigm, subjects were either disadvantaged by a harmdoer or by external events and received compensation that either was or was not accompanied by a request for repayment. When subjects had been disadvantaged by external events, they were more satisfied and felt more fairly treated when there was an opportunity for reciprocation than when there was not, while the opposite pattern was the case when the harmdoer was responsible for the disadvantage. The results were discussed in the context of the complexity of the receipt of aid phenomenon and possible implications for the design of ameliorative social programs.     

Reflections on the meaning of a Semester at Sea voyage after twenty-two years

22 years after completion of a travel-study voyage around the world, a random sample of 29 participants was contacted by telephone and mail to reflect on the meaning of the experience. Respondents answered open-ended questions about their lives and outcomes of Semester at Sea, and they completed Crumbaugh's Purpose in Life Test based on Frankl's concepts. Participants maintained a global perspective and high test scores. Life events such as parenthood and major accomplishments were related to further discovery of meaning. Research earlier in the lives of participants suggested that Semester at Sea was a springboard for personal growth. Within a lifespan developmental model, as participants approach middle age, a more accurate metaphor for the meaning of the Semester at Sea experience may be an interwoven strand in a life composition.     

An Integral Psychology Response to Helminiak's (2001) “Treating Spiritual Issues in Secular Psychotherapy”

This article is a response to D. A. Helminiak's (2001) “Treating Spiritual Issues in Secular Psychotherapy” from the perspective of K. Wilber's integral psychology. The article consists of 3 sections: (a) a selective summary of integral psychology, including the perennial philosophy, 10 levels of development, lines of development, temporary states, types of orientations, the self, and the 4 quadrants; (b) various conceptual issues; and (c) usefulness to mental health practitioners (MHPs). Although D. A. Helminiak's endeavor to formulate a clear and functional definition of spirituality is commended, his claim of novelty is shown to be unwarranted. It is argued that K. Wilber's integral model is more comprehensive, clear, coherent, and helpful to MHPs.     

History of the Hospital Real y General de Nuestra Señora de Gracia in Saragossa: Occupational Therapy Pioneer in Neurology and Psychiatry in Spain

In this article the authors describe the program of the Hospital Real y General de Nuestra Señora de Gracia in Saragossa (Spain) and its importance in the history of occupational therapy. It is believed to be the first hospital in the world to use occupations as therapy for psychiatric patients. Pinel knew about this new trend through a report by Iberti and wrote about it in his book Medico-Philosophical Treatise on Mental Alienation.     

Investigating the Links Between Cultural Values and Belief in Conspiracy Theories: The Key Roles of Collectivism and Masculinity

Research suggests that belief in conspiracy theories (CT) stems from basic psychological mechanisms and is linked to other belief systems (e.g., religious beliefs). While previous research has extensively examined individual and contextual variables associated with CT beliefs, it has not yet investigated the role of culture. In the current research, we tested, based on a situated cultural cognition perspective, the extent to which culture predicts CT beliefs. Using Hofstede's model of cultural values, three nation-level analyses of data from 25, 19, and 18 countries using different measures of CT beliefs (Study 1, N = 5323; Study 2a, N = 12,255; Study 2b, N = 30,994) revealed positive associations between masculinity, collectivism, and CT beliefs. A cross-sectional study among U.S. citizens (Study 3, N = 350), using individual-level measures of Hofstede's values, replicated these findings. A meta-analysis of correlations across studies corroborated the presence of positive links between CT beliefs, collectivism, r = .31, 95% CI = [.15; .47], and masculinity, r = .39, 95% CI = [.18; .59]. Our results suggest that in addition to individual differences and contextual variables, cultural factors also play an important role in shaping CT beliefs.     

Family Functioning,Parental Psychological Distress and Child Behaviours: Evidence from the Victorian Child Health and Wellbeing Study

We examined, using data from the 2006 Victorian Child Health and Wellbeing Study (VCHWS), whether family functioning is associated with parental psychological distress and children's behavioural difficulties. The VCHWS was a statewide cross‐sectional telephone survey to 5,000 randomly selected primary caregivers of 0‐ to 12‐year‐old children between October 2005 and March 2006. Only parents or guardians of children aged 4–12 years (n = 3,370) were included in this study. After adjusting for sociodemographic variables and ethnicity, parents or guardians scoring higher on the family functioning scale (i.e., from poorly functioning households) were at greater risk of psychological distress and had children with lower levels of prosocial behaviour and higher levels of behavioural difficulties relative to those from healthily functioning households. Mental health prevention programmes addressing child mental and conduct problems should consider the family environment and target those families functioning poorly.     

A brief intervention to increase physical activity behavior among adolescents using mental simulations and action planning

This study evaluated the effectiveness of a brief integrated theory-based intervention to increase physical activity (PA) among adolescents over a three-month follow-up period. A 2 (mental simulation: present vs. absent) × 2 (action planning: present vs. absent) × 4 (time: baseline vs. one-month vs. two-month vs. three-month follow-up) mixed-model randomized controlled design was adopted. Adolescents aged 14–15 years (N = 267) completed baseline psychological measures and self-reported PA followed by the relevant intervention manipulation, if appropriate, with follow-up measures collected one, two, and three months later. Results revealed no significant effects for the mental simulation and action planning strategies nor the interaction of the two strategies. However, among participants with low levels of baseline PA, participants in both mental simulation alone and action planning alone groups reported significantly higher levels of PA at one-month follow up than other groups, suggesting that individual intervention components may be effective in low-active adolescents.     

Visual motion disambiguation by a subliminal sound

There is growing interest in the effect of sound on visual motion perception. One model involves the illusion created when two identical objects moving towards each other on a two-dimensional visual display can be seen to either bounce off or stream through each other. Previous studies show that the large bias normally seen toward the streaming percept can be modulated by the presentation of an auditory event at the moment of coincidence. However, no reports to date provide sufficient evidence to indicate whether the sound bounce-inducing effect is due to a perceptual binding process or merely to an explicit inference resulting from the transient auditory stimulus resembling a physical collision of two objects. In the present study, we used a novel experimental design in which a subliminal sound was presented either 150 ms before, at, or 150 ms after the moment of coincidence of two disks moving towards each other. The results showed that there was an increased perception of bouncing (rather than streaming) when the subliminal sound was presented at or 150 ms after the moment of coincidence compared to when no sound was presented. These findings provide the first empirical demonstration that activation of the human auditory system without reaching consciousness affects the perception of an ambiguous visual motion display.
