Phonotactic probability influences speech production

Speakers are faster and more accurate at processing certain sound sequences within their language. Does this reflect the fact that these sequences are frequent or that they are phonetically less complex (e.g., easier to articulate)? It has been difficult to contrast these two factors given their high correlation in natural languages. In this study, participants were exposed to novel phonotactic constraints de-correlating complexity and frequency by subjecting the same phonological structure to varying degrees of probabilistic constraint. Participants' behavior was sensitive to variations in frequency, demonstrating that phonotactic probability influences speech production independent of phonetic complexity.     

As It Was in the Beginning: Death and Re-membrance and the Christian Intuition

The author argues that the psyche crafts an affective metaphor for death out of the separation drama of infancy. Emergence of self from the mother–infant dyad can accomplish cohesion of fragmentary unconscious mentation strong enough, following Winnicott, to make possible a belief in God. Through developmental synergy between female and male elements, a sense of participation in an eternal principle of being can be achieved, sustaining the ego against anxieties over disintegration, and death as its analog. Myths of the child god illuminate the equation of fragmentation with death of self. Christianity expresses how the cohered self can transcend fragmentation.     

Implicit memory: a prime example for brand consideration and choice

Three experiments investigated the influence of implicit memory for familiar brand names on consumer choice. Priming was measured using modified preference judgment tasks that comprised both brand consideration and choice components. Experiment 1 used a ‘complex choice task’ where consideration and choice stages were characterized as acting in sequence. Experiment 2 explored a different formulation whereby consideration and choice were assumed to act in parallel. Both experiments demonstrated that priming had an influence on brand consideration but not on final or preferred choice. Finally, Experiment 3 replicated and extended these findings under more realistic conditions where participants actually received some of the products that they selected. Overall, the experiments suggested that for many decisions involving the consideration of familiar brands prior to choice, previous exposure to brand names can increase the likelihood that they will enter the consumers' consideration set. However, the advantage does not appear to extend to choice itself. Copyright © 2004 John Wiley & Sons, Ltd.     

Understanding the relationship between repetition priming and mere exposure

Over the last two decades interest in implicit memory, most notably repetition priming, has grown considerably. During the same period, research has also focused on the mere exposure effect. Although the two areas have developed relatively independently, a number of studies has described the mere exposure effect as an example of implicit memory. Tacit in their comparisons is the assumption that the effect is more specifically a demonstration of repetition priming. Having noted that this assumption has attracted relatively little attention, this paper reviews current evidence and shows that it is by no means conclusive. Although some evidence is suggestive of a common underlying mechanism, even a modified repetition priming (perceptual fluency/attribution) framework cannot accommodate all of the differences between the two phenomena. Notwithstanding this, it seems likely that a version of this theoretical framework still offers the best hope of a comprehensive explanation for the mere exposure effect and its relationship to repetition priming. As such, the paper finishes by offering some initial guidance as to ways in which the perceptual fluency/attribution framework might be extended, as well as outlining important areas for future research.     

A lifespan database of adult facial stimuli.

Faces constitute a unique and widely used category of stimuli. In spite of their importance, there are few collections of faces for use in research, none of which adequately represent the different ages of faces across the lifespan. This lack of a range of ages has limited the majority of researchers to using predominantly young faces as stimuli even when their hypotheses concern both young and old participants. We describe a database of 575 individual faces ranging from ages 18 to 93. Our database was developed to be more representative of age groups across the lifespan, with a special emphasis on recruiting older adults. The resulting database has faces of 218 adults age 18-29, 76 adults age 30-49, 123 adults age 50-69, and 158 adults age 70 and older. These faces may be acquired for research purposes from http://agingmind.cns.uiuc.edu/facedb/. This will allow researchers interested in using facial stimuli access to a wider age range of adult faces than has previously been available.     

Psychological,sociocultural, and marital adaptation of Turkish immigrant couples in Canada

The study examined the acculturation and adaptation of 200 married Turkish immigrants in Toronto, Canada, using self‐report questionnaires. As an extension of research from sojourners to immigrants, and from individuals to married couples, marital adaptation was introduced and three facets of adaptation were differentiated: psychological, sociocultural, and marital. The findings support the contention that adaptation is multifaceted. Consistent with stress and coping models, psychological adaptation of married couples was associated with the personality variable of hardiness, social support, acculturation attitudes, and discrimination. On the other hand, in line with social learning perspectives, sociocultural adaptation was mostly related to the variables instrumental in acquiring social skills in the new culture, namely, language proficiency and contact with members of the dominant group. Marital adaptation was mostly associated with marital stressors and marital support. The lack of research on gender differences in the differentiation of adaptation was addressed. This differentiation was clearer in men than in women; there were also different variables associated with the facets of men's and women's adaptation. The effects of socioeconomic status and gender have also been examined. The findings made it evident that Turkish immigrants did not acculturate uniformly. Two groups of Turkish immigrants, working class and professionals were clearly distinguished in their acculturation experiences and adaptation. Gender differences were most apparent in the low socioeconomic status group. Women in general were psychologically more vulnerable than men; the group that faced more risk factors were those women of low socioeconomic status. In terms of acculturation attitudes, Turkish immigrant couples strongly endorsed separation; however, those of high socioeconomic status preferred integration and assimilation to a greater, and separation to a lesser extent than those of low socioeconomic status.     

Spatial learning in pigs: effects of environmental enrichment and individual characteristics on behaviour and performance

This study investigated the effects of both environmental enrichment and individual behavioural characteristics on spatial cognitive capabilities of pigs, using a novel latent spatial learning paradigm based on Tolman’s detour experiments (1948). Pigs were housed either in ‘barren’ pens or in pens enriched with straw bedding from birth. Pigs were restrained in a Backtest at 10 and 17 days postpartum. Based on their escape behaviour in this test, which has been shown to reflect their behavioural style, six ‘high-resisting’(HR) and six ‘low-resisting’ (LR) pigs were selected from each housing environment (n = 24 in total). At 12 weeks of age, pairs of pen mates (LR and HR) were exposed to a maze three times (exploration trials). Pigs were then placed individually in the maze, and social reinstatement proved to be a strong incentive to find the exit leading to the home pen. We subsequently blocked the direct route to the exit, forcing animals to find a detour (memory test 1, MT1). This test was repeated once to investigate the relative improvement, i.e. detour learning (memory test 2, MT2). Housing condition and Backtest response strongly affected exploration patterns. In spite of this, no effects on performance during the subsequent memory tests were found. Performance was substantially improved in MT2, indicating that once a goal is apparent, pigs are able to solve a complex spatial memory task easily. In conclusion, social reinstatement provided a good incentive to complete a spatial task, and the substantial improvement in performance between MT1 and MT2 stresses the need for task complexity when testing spatial memory in pigs. Housing conditions or individual behavioural style did not affect spatial memory during MT1 or MT2. However, housing environment and behavioural style strongly affected explorative behaviour of pigs in an unfamiliar maze during both exploration trials and memory tests. This implicates that apparent effects of environmental enrichment on spatial learning and memory in pigs might reflect differences in explorative patterns rather than in cognitive processes.     

Stuart’s tau measure of effect size for ordinal variables: Some methodological considerations

The reporting of measures of effect size has become increasingly important in psychology. A Monte Carlo resampling permutation procedure is introduced to find near-optimum maximum values for Stuart’s τ _c measure for two-way ordinal contingency tables, also termed Kendall’s τ _c since Kendall introduced τ _a and τ _b . Comparisons between resampling and exact procedures demonstrate the accuracy and utility of resampling measures of effect size for two-way ordinal contingency tables. The resampling procedure is shown to be more precise than the traditional method of standardizing τ _c .     

Configural Approaches to Temperament Assessment: Implications for Predicting Risk of Unintentional Injury in Children

ABSTRACT This study used two configural approaches to understand how temperament factors (surgency/extraversion, negative affect, and effortful control) might predict child injury risk. In the first approach, clustering procedures were applied to trait dimensions to identify discrete personality prototypes. In the second approach, two- and three-way trait interactions were considered dimensionally in regression models predicting injury outcomes. Injury risk was assessed through four measures: lifetime prevalence of injuries requiring professional medical attention, scores on the Injury Behavior Checklist, and frequency and severity of injuries reported in a 2-week injury diary. In the prototype analysis, three temperament clusters were obtained, which resembled resilient, overcontrolled, and undercontrolled types found in previous research. Undercontrolled children had greater risk of injury than children in the other groups. In the dimensional interaction analyses, an interaction between surgency/extraversion and negative affect tended to predict injury, especially when children lacked capacity for effortful control.
