Age,working memory,and the Tower of London task

The current study explores the role of three components of working memory in age differences in an executive task, the Tower of London (TOL). The TOL task is sensitive to frontal lobe damage, and is widely used to measure planning ability. Dual tasks were used to test the involvement of the phonological loop (articulatory suppression), visuospatial buffer (pattern tapping), and central executive (random generation) in age effects on the TOL. Older adults showed greater reliance than young on domain-specific verbal and spatial memory components in performing the TOL. In terms of executive function, qualitatively different interference patterns were seen in young and old participants. However, the validity of using random generation tasks to assess executive function in older populations can be questioned. For older participants, performing the TOL loads all components of working memory, whereas for the younger participants the TOL more specifically loads executive functioning.     

Photographic Individuality, Breadth of Perspective, and Creativity

Individuality is valued in most conceptions of personality, but is seldom operationalized. The present research used photo essays about the self as the medium for operationalizing self-construals that are unlike others (i.e., are uniquely creative, abstract, self-reflective, and multidimensional). Ratings of these photo essays from two samples ( N = 183 university students) served as the measure of individuality. This measure was predicted and found to correlate in both samples with Breadth of Interest from the Jackson Personality Inventory (JPI; Jackson, 1994). In Study 1, individuality also correlated with the JPI Complexity scale and with two measures of divergent thinking (unique word associations, and fluency on Wallach & Kogan's [1965] creativity tasks). In Study 2, individuality correlated with having more permeable boundaries, a nonprejudicial universal orientation, and imagining greater cultural diversity in one's future. Results suggest that individualistic persons take a broader, more complex and more creative perspective to their lives.     

Concordance in attachment states of mind and styles with respect to fathers and mothers

It is believed that by adulthood, independent attachments to the mother and the father coalesce into a single state of mind with respect to attachment. If true, states of mind with respect to mothers and fathers should be concordant. Fifty-six young adults were administered two versions of the Adult Attachment Interview, each of which asked about their relationship with one parent. State of mind with respect to the father was significantly related to state of mind with respect to the mother, as were attachment styles regarding the two parents. Perceptions of attachment styles were not very related to corresponding states of mind but were related to inferred loving from a parent.     

Phonemes, rimes, vocabulary, and grammatical skills as foundations of early reading development: evidence from a longitudinal study

The authors present the results of a 2-year longitudinal study of 90 British children beginning at school entry when they were 4 years 9 months old (range = 4 years 2 months to 5 years 2 months). The relationships among early phonological skills, letter knowledge, grammatical skills, and vocabulary knowledge were investigated as predictors of word recognition and reading comprehension. Word recognition skills were consistently predicted by earlier measures of letter knowledge and phoneme sensitivity (but not by vocabulary knowledge, rhyme skills, or grammatical skills). In contrast, reading comprehension was predicted by prior word recognition skills, vocabulary knowledge, and grammatical skills. The results are related to current theories about the role of phonological, grammatical, and vocabulary skills in the development of early reading skills.     

The role of dopamine in reinforcement: changes in reinforcement sensitivity induced by D1-type, D2-type, and nonselective dopamine receptor agonists

Dose-dependent changes in sensitivity to reinforcement were found when rats were treated with low, moderate, and high doses of the partial dopamine D1-type receptor agonist SKF38393 and with the nonselective dopamine agonist apomorphine, but did not change when rats were treated with similar doses of the selective dopamine D2-type receptor agonist quinpirole. Estimates of bias did not differ significantly across exposure to SKF38393 or quinpirole, but did change significantly at the high dose of apomorphine. Estimates of goodness of fit (r2) did not change significantly during quinpirole exposure. Poor goodness of fit was obtained for the high doses of SKF38393 and apomorphine. Decrements in absolute rates of responding were observed at the high dose of quinpirole and at the moderate and high doses of SKF38393 and apomorphine. Changes in r2 and absolute responding may be due to increases in stereotyped behavior during SKF38393 and apomorphine exposure that, in contrast to quinpirole, were distant from the response lever. The present data provide evidence that sensitivity to reward is affected more strongly by dopamine D1-like receptors rather than D2-like receptors, consistent with evidence from other studies investigating consummatory dopamine behavior and the tonic/phasic dopamine hypothesis.     

Difference and Repetition in <Emphasis Type="Italic">Both Sitting Duet</Emphasis>

In this paper I identify and explore resonances between a contemporary dance piece – Jonathan Burrowss and Matteo Fargions Both Sitting Duet (2003) – and some theories from Gilles Deleuzes Difference and Repetition (1994). The duet consists of rhythmic, repetitive patterns of mainly hand movements performed by two men, for the most part, sitting on chairs. My argument, with Deleuze, is that the repetitions in the dance are productive rather than reductive. They are never repetitions of the same. The ways in which the hand patterns are played with constitute the multiple differences and repetitions we witness. I discuss these in relation to Deleuzes theories of repetition, specifically the ways in which repetition differs from resemblance avoiding the limitations of notions of origin and representation. I argue that, because of these differences which are bound up in the affective qualities of the duet that characterise the distinctive relationship between the two performers, the work, like Deleuzes theories, is transgressive with potential for change. I demonstrate this through its resonances with Deleuzes notions of simulacra and importantly his discussion of the Other. In the process, I aim to show how dance and philosophy can open up something of each other and, in this instance, suggest ways of thinking encounters otherwise. My aim is to foreground the transgressive potential of the extended repetition of the dance for making differences that matter between self and other.     

On the outside looking in: loneliness and social monitoring

The skill-deficit view of loneliness posits that unskilled social interactions block lonely individuals from social inclusion. The current studies examine loneliness in relation to social attention and perception processes thought to be important for socially skilled behavior. Two studies investigate the association between social monitoring (attention to social information and cues) and self-reported loneliness and number of close social ties. In Study 1, higher levels of loneliness are related to increased rather than decreased incidental social memory. In Study 2, individuals with fewer reported friends show heightened decoding of social cues in faces and voices. Results of these studies suggest that the attentional and perceptual building blocks of socially skilled behavior remain intact, and perhaps enhanced, in lonely individuals. Implications for recent models of belonging regulation and theories of loneliness are discussed.     

Publication rates of male and female academic clinical psychologists in California

Compared here was the publication rate of men and women surveyed by mail (480 academic clinical psychologists in California) regarding number of publications, self-perception of their role of researcher versus teacher, variables related to research opportunity (grants, time spent in research), and type of institution in which they are employed. The men had 1.6 as many publications per year as did the women, and the semipartial correlation was -.21 for sex in the last step of a multiple regression and accounted for an additional 4% of the variance. Thus, the men published more, even when ostensible opportunities were controlled. For this sample variables of sex and self-perception of role of researcher versus teacher were more highly correlated with number of publications than were the research opportunity variables of grants, time spent in research, and type of academic institution of employment.     

A methodology for assessing the functions of emerging speech in children with developmental disabilities

An approach based on Skinner's (1957) theory of verbal behavior has been developed to understand and teach elementary communication skills to children with autism and developmental disabilities (Sundberg & Partington, 1998). However, few studies have directly examined the characteristics of emerging language in children with developmental disabilities. The purpose of this study was to develop and evaluate an assessment for identifying the elementary functions of vocal speech in children. Participants were 4 children with developmental disabilities, aged 6 years to 12 years, who exhibited at least one distinguishable vocal response (word or phrase) frequently in the natural environment. The assessment focused on three verbal operants delineated by Skinner (mand, tact, and intraverbal). One or more functions were identified for at least one vocal response of each child. Results suggested that this assessment would be useful for (a) evaluating Skinner's theory, (b) guiding decisions about language training for individual children, and (c) studying the nature of expressive language development in children with developmental disabilities.     

The man who listens to behavior: folk wisdom and behavior analysis from a real horse whisperer

The popular novel and movie The Horse Whisperer are based on the work of several real-life horse whisperers, the most famous of whom is Monty Roberts. Over the last 50 years, Roberts has developed a technique for training horses that is both more effective and less aversive than traditional training techniques. An analysis of Roberts' methods (as described in his book, The Man Who Listens to Horses) indicates a deep understanding of behavioral principles including positive reinforcement, timeout, species-specific defense reactions, “learned helplessness,” and the behavioral analysis of language. Roberts developed his theory and techniques on the basis of personal experience and folk wisdom, and not as the result of formal training in behavior analysis. Behavior analysts can clearly learn from such insightful yet “behaviorally incorrect” practitioners, just as such practitioners can benefit from the objective science of behavior analysts.
