The role of age of acquisition in memory: effects on judgements of learning and recall

Judgements of learning (JOLs) are self-made predictions of the likelihood that one will later recall information. The influence of stimulus characteristics on JOLs and recall continues to receive attention, yet there are still a number of unexplored lexical word features that may exert an effect on mnemonic processing. Using a standard cue-target paradigm, we focused on the role of word age of acquisition (AoA) and evaluated the role of both cue and target AoA on responses. We replicated the robust delayed-JOL effect and used a novel items analysis approach to examine the relationship between intrinsic word features and accuracy and reaction times for both JOLs and recall. A consistent effect of target AoA was found, even after controlling for a range of covariates previously shown to impact JOLs and recall. These results expand the role of AoA in word processing and suggest that it is a key variable in memory and metacognition; they also support Koriat's (1997) cue utilization framework.     

“White” or “European American”? Self-identifying labels influence majority group members' interethnic attitudes

Multiculturalism (i.e., the recognition and celebration of cultural differences) has many potential benefits for society, including reduced prejudice among nonminorities and increased psychological well-being among ethnic minorities. Yet nonminorities generally tend to resist multiculturalism more than do minorities and believe that it is irrelevant to them. Two studies were conducted to examine why and under what conditions this is the case. In both studies, nonminority participants were randomly assigned to mark their race/ethnicity as either “White” or “European American” on a demographic survey, before answering questions about their interethnic attitudes. Results demonstrated that nonminorities primed to think of themselves as White (versus European American) were subsequently less supportive of multiculturalism and more racially prejudiced, due to decreases in identification with ethnic minorities. Implications for how to improve nonminorities' attitudes toward multiculturalism are discussed.     

Socially motivated projection: Need to belong increases perceived opinion consensus on important issues

In three studies, we tested whether the need to belong would motivate people to perceive consensus for their opinions on important social issues. In Study 1, a nationally representative telephone survey, participants with a high dispositional need to belong perceived greater consensus for their opinions on immigrant naturalization than did those with a low need to belong. However, this relationship was strongest among participants who reported that the issue was personally important to them. In Study 2, participants primed with rejection‐related (versus acceptance‐related) words, and who reported high levels of issue importance, demonstrated greater false consensus for their opinions on a proposed alcohol tax increase. In Study 3, participants who received random feedback that they held a common (versus uncommon) opinion had a lower subsequent need to belong when the issue was important to them, suggesting that consensus perceptions can in fact mitigate belongingness needs.

Applying Science and Applied Science: What’s the Difference?

Prandtl’s work on the boundary layer theory is an interesting example for illustrating several important issues in philosophy of science such as the relation between theories and models and whether it is possible to distinguish, in a principled way, between pure and applied science. In what follows I discuss several proposals by the symposium participants regarding the interpretation of Prandtl’s work and whether it should be characterized as an instance of applied science. My own interpretation of this example (1999) emphasised the degree of autonomy embedded in Prandtl’s boundary layer model and the way it became integrated in the larger theoretical context of hydrodynamics. In addition to extending that discussion here I also claim that the characterization of applied science which formed the basis for the symposium does not enable us to successfully distinguish applied science from the general practice of ‘applying’ basic scientific knowledge in a variety of contexts.     

The Satir Model with Female Adult Survivors of Childhood Sexual Abuse

Child sexual abuse is a recognized problem in the United States and Canada. There are several approaches to therapy with adult survivors of childhood sexual abuse. This article discusses Virginia Satir's model of therapy as it applies to sexual abuse. The emphasis of the Satir model is on transforming the impact of the abuse, no matter how the client chooses to process her relationship with the abuse, and is illustrated through a case study.     

On learning to move randomly

In 2 experiments, the authors examined whether and to what degree young adults can learn to produce random planar motion of the index finger or fingers. Three different types of information feedback were provided to the participants (N = 8 in each experiment) over up to 5 days of practice across the 2 experiments. The results from both experiments revealed that the participants produced a relatively low level of movement randomness in finger motion and that they did not learn through practice to enhance the stochastic properties of their movement under any feedback conditions. The findings provide further evidence that there are relatively tight constraints on the number of dimensions that are regulating single-limb planar motion and that those constraints are not susceptible to change through typical learning protocols.     

The effects of focus of attention on attributional bias in patients experiencing auditory hallucinations

Cognitive models suggest that auditory hallucinations occur as the result of internal events attributed to an external source. The present study represents an attempt to evaluate the source monitoring performance of people who experience auditory hallucinations, specifically in terms of the suggested links between source monitoring, emotionality of stimuli and self-focused attention. The source monitoring performance of a group of 30 patients with a diagnosis of a schizophrenia spectrum disorder who experience auditory hallucinations was compared following successful experimental manipulation of their attention, designed to increase and decrease their levels of self-focused attention. The inclusion of words previously rated as emotionally salient by schizophrenic patients assessed the effect of emotionality on source monitoring performance. This study demonstrated that participants' ratings of both internality and control of their responses to the word association task were lower in the external focus condition than the internal focus condition. Furthermore, it was found that ratings of internality and control were lower for responses to both positive and negative stimuli compared to responses to neutral stimuli, and the magnitude of these differences was amplified in the internal focus condition relative to the external focus condition. Focus of attention has a significant effect on source monitoring performance in people experiencing auditory hallucinations. The theoretical and clinical implications of these findings are discussed.     

Personality assessment in neuropsychology: the nonspecificity of MMPI-2 neurocorrection methods

Three established methods of neurocorrection claim to improve Minnesota Multiphasic Personality Inventory (MMPI)/MMPI-2 validity with closed-head injury (CHI) patients. These methods (which suggest removing "neurological" items from scoring) were employed here comparing 35 CHI patients with 35 psychiatric patients with elevated profiles. The 14-item correction changed 2-point codes for 41% of CHI and 31% of psychiatric profiles, the 30-item system changed 77% of CHI and 71% of psychiatric profiles, whereas the 37-item system changed 80% of CHI and 71% of psychiatric profiles. There were no significant differences between the two groups in number of profiles changed or number of neurocorrective items endorsed. Using each of the three correction systems, the following percentage of profiles remained elevated: 99%, 87%, and 89%, respectively.
