Task characteristics and the contextual interference effect

The purpose of this exploratory study was to examine the influence of blocked and random practice on the acquisition and retention of a criterion multisegment motor task practiced alongside either two similar-distractors tasks or two different-distractors tasks. The random-practice similar-distractors group made more decision-making errors and performed the criterion task more slowly than the blocked-practice similar-distractors group during the acquisition phase. Following a brief filled retention interval, the blocked-practice similar-distractors group demonstrated a loss of acquired performance capabilities, whereas the random-practice similar-distractors group did not. The blocked- and random-practice different-distractors groups performed similarly throughout the experiment. Results are interpreted within Glenberg's component-levels theory, in which it was argued that random practice must stimulate the differential storage of multilevel contextual components associated with the multiple motor tasks being learned to produce a contextual interference effect. The theoretical and practical implications of differential storage versus nonrepetition as a function of random practice are discussed.     

A priori causal laws

Sober and Elgin defend the claim that there are a priori causal laws in biology. Lange and Rosenberg take issue with this on Humean grounds, among others. I will argue that Sober and Elgin don’t go far enough – there are a priori causal laws in many sciences. Furthermore, I will argue that this thesis is compatible with a Humean metaphysics and an empiricist epistemology.     

Culturally Focused Community‐Centered Service Learning: An International Cultural Immersion Experience

An immersion training model is described that incorporates culturally focused community‐centered service in South Africa as an experiential learning approach. Recommendations for developing international cultural immersion training with a goal of developing cultural competencies are suggested. Se describe un modelo formativo de inmersión que incorpora servicios culturalmente enfocados centrados en la comunidad en Sudáfrica como una aproximación experimental de aprendizaje. Se sugieren recomendaciones para desarrollar programas formativos de inmersión cultural con el objetivo de desarollar competencias culturales.     

Working memory deficits can be overcome: Impacts of training and medication on working memory in children with ADHD

This study evaluated the impact of two interventions—a training program and stimulant medication—on working memory (WM) function in children with attention deficit hyperactivity disorder (ADHD). Twenty‐five children aged between 8 and 11 years participated in training that taxed WM skills to the limit for a minimum of 20 days, and completed other assessments of WM and IQ before and after training, and with and without prescribed drug treatment. While medication significantly improved visuo‐spatial memory performance, training led to substantial gains in all components of WM across untrained tasks. Training gains associated with the central executive persisted over a 6‐month period. IQ scores were unaffected by either intervention. These findings indicate that the WM impairments in children with ADHD can be differentially ameliorated by training and by stimulant medication. Copyright © 2009 John Wiley & Sons, Ltd.     

Attributions for Health‐Related Physical Activity

Tenets of Weiner's (1985, 1986 ) attribution theory were examined in the context of being active enough for health benefits, including associations between attributions, emotions, and future expectations. Participants completed questionnaires assessing activity, perceived success/failure to be active enough for health benefits, attributions, emotions, and future expectancy. Perception of being active enough for health benefits was associated with more internal, personally controllable, and stable attributions. Support was found for relationships between perceived outcome and emotions, but not for attributions and emotions. Finally, a positive relationship was found between stability of attributions and certainty of achieving similar future activity outcomes. Given the interest in promoting activity for health, examining attributions for being sufficiently active for health may be considered an important advance.     

Might an overweight waitress make you eat more? How the body type of others is sufficient to alter our food consumption

This paper investigates how people's food choices can be shaped by the body type of others around them. Using a professionally constructed obesity prosthesis, we show that the body type of a (confederate) server in a taste test study was sufficient to alter both the quantity (Experiment 1) and specific choices (Experiment 2) participants made but that chronic dieters and non-dieters exhibited opposite effects. While non-dieters ate more snacks when the server was thin, dieters ate more when the server was heavy. Dieters were also more persuaded by a heavy (vs. a thin) server, choosing both a healthy and unhealthy snack more often when she recommended it to them. We suggest these results may be attributable to identification with the server.     

When There Is Not Enough to Go Around: How Black People’s Perceptions of Competition for Black Mates Affects Forced Black Identity Ascriptions of Black/White Multiracial People

Using a resource scarcity framework, the current study investigated whether Black people’s perceptions of competition for Black mates related to ascribing a Black identity onto Black/White Multiracial people. Participants took online questionnaires that assessed competition for Black mates, likelihood of forcing a Black identity onto a self-identified Black/White Multiracial person, essentialism, and contact with Multiracial people. Results indicated that increased perceptions of competition for Black mates was related to increased forced Black identity onto self-identified Black/White Multiracial people, above and beyond levels of essentialism and contact. This relationship was stronger for sexual minorities. The current research supports the proposition that scarcity of resources (i.e., mates) affects ideologies regarding Black/White Multiracial people’s identities.     

Phenomenology and Critical Social Psychology: Directions and Debates in Theory and Research

There has been significant growth in critical approaches to social psychology in recent years. Phenomenological, discursive and psychoanalytically informed perspectives, amongst others, have become increasingly popular alternatives to ‘mainstream’ cognitive social psychology. This paper describes the fundamental philosophy and methodology underpinning phenomenological psychology along with discussion of a number of key issues in qualitative research in social psychology. In particular, I discuss the role of interpretation, the turn to language and need for political engagement within critical social psychology. More recently, there has been a growth in phenomenologically informed narrative theories and methodologies and in this paper I introduce my own development of a critical narrative analysis. In the process I discuss some of the most pressing debates about research within the phenomenological tradition and provide rebuttals, solutions and possible future directions for phenomenological theory and research that may lead to yet greater recognition for this social psychological perspective.
