The Apartment Test: validity of a memory measure

The Memory in Reality (MIR) test, or Apartment Test, was designed as an ecologically valid alternative to word list recall measures. Participants name 10 everyday objects, place them in a scale model of an apartment and after a delay with interference, recall the objects and their placement. Two studies are reported. Study 1 included 51 older adult volunteers. Study 2 was a population-based sample of 633 older twins. The Apartment Test Recall and Placement tasks were highly correlated with word list delayed recall. Ecological validity was supported by correlations with informant reports of participants' functioning. Apartment Test Recall was not affected by education. Analysis of Receiver Operating Characteristics (ROC) showed Apartment Test Recall performed as well as word list delayed recall in distinguishing participants with and without dementia. We conclude that the Apartment Test is a valid measure of verbal memory with evidence of ecological and concurrent validity.     

Food sharing and feeding another person suggest intimacy; two studies of American college students

Ethnographic work indicates that food transfer has social significance, but food transfer has not previously been considered as a nonverbal communication channel. We categorize social food transfer along two dimensions: nature of the behaviour in the transfer (X shares food with or feeds Y), and the state of the food transferred (Y's food never contacted by X, or Y's food previously bitten/tasted/touched by X; we call the latter food consubstantiation (shared substance)). These two dimensions generate the four conditions investigated in this study: no sharing, sharing, sharing with consubstantiation, and feeding. The social significance of these types of situations was assessed in two ways. American college students indicated in a questionnaire both the extent to which they transfer food within different relationships, and what they took to be normative among American college students. Second, a different group of students participated in an Asch impression study in which they observed a videotape of two young adults of opposite sex eating at a restaurant, with the variable across subjects being the four conditions designated above. Viewers were asked to assess the relationship between the young adults, and to rate the degree of intimacy between the adults in terms of mutual feelings and acts of intimacy (e.g. sharing drinks, touching, having sexual relations). Results from both studies are congruent, and indicate that sharing implies a positive/friendly social relationship, and feeding implies a stronger, often romantic relationship. Consubstantiation superimposed on sharing modestly increased judgments of intimacy and closeness of relationship. © 1998 John Wiley & Sons, Ltd.     

The structure of social substitutions: a test of relational models theory

People often select a substitute to replace an intended interactant, thereby revealing how they represent their social intentions. Naturally-occurring substitutions preserved the relational model governing the interaction but not the characteristics of individual participants, indicating that social intentions are formulated in terms of relational rather than individual characteristics. © 1997 John Wiley & Sons, Ltd.     

System-justifying ideologies moderate status = competence stereotypes: roles for belief in a just world and social dominance orientation

High-status outgroups tend to be stereotyped as competent, while low-status groups tend to be stereotyped as incompetent. These stereotypes provide legitimacy to hierarchical social systems. However, research to date has tended to focus on the socio-structural correlates and cross-cultural stability of these stereotypes, emphasising universality over malleability. The current research demonstrates that, although strong, the association between status and competence, but not status and warmth, is moderated by ideological beliefs and attitudes towards inequality. In two studies, participants high in belief in a just world (BJW) or social dominance orientation (SDO) were more likely than those low in BJW or SDO to view a high-status target as more competent than a low-status target. Findings support the view that status stereotypes justify social inequalities, and demonstrate that they are sensitive to ideological orientations. Implications for theory and research on status and power stereotypes are discussed. Copyright © 2007 John Wiley & Sons, Ltd.     

Assessing the Role of Active Student Response During Error Correction in Discrete Trial Instruction

Research generally supports the use of error-correction procedures that require active student responses (ASRs). However, some recent research suggests that requiring ASRs after errors is not always advantageous for individuals with autism spectrum disorder (ASD). We examined acquisition in a receptive identification task for two learners with ASD under three error-correction conditions: required ASRs, model, and modified model that minimized spontaneous ASR. In the model condition, both individuals emitted spontaneous responses to the model even though none was required, extending previous research to the receptive domain. For both learners, the model error-correction was effective; however, minimizing the spontaneous ASR in the modified model condition impacted its efficacy compared to the required ASR condition for one learner. For the other learner, error-correction procedures that required ASRs were not effective. Results are discussed in terms of empirical evaluation of error-correction procedures and suggest that imitative behavior (e.g., emitting an ASR when none is required) might function as a prerequisite skill that predicts the efficacy of model-based error-correction procedures for learners with ASD.     

A self-help book is better than sleep hygiene advice for insomnia: a randomized controlled comparative study

The objective was to compare the effects of two types of written material for insomnia in a randomized trial with follow-up after three months. Insomniacs were recruited through newspaper advertisements to a web-based survey with validated questionnaires about sleep, anxiety, depression, and use of sleep medications. A self-help book focusing on cognitive behavioral therapy for insomnia was compared to standard sleep hygiene advice; 77 and 78 participants were randomized to self-help book or sleep hygiene advice, respectively. The response rate was 81.9%. The self-help book gave significantly better scores on the sleep questionnaires compared to sleep hygiene advice. The proportion using sleep medications was reduced in the self-help book group, whereas it was increased in the sleep hygiene group. Compared to pre-treatment, the self-help book improved scores on the sleep (effect sizes 0.61-0.62) and depression (effect size 0.18) scales, whereas the sleep hygiene advice improved scores on some sleep scales (effect sizes 0.24-0.28), but worsened another (effect size -0.36). In addition, sleep hygiene advice increased the number of days per week where they took sleep medications (effect size -0.50). To conclude, in this randomized controlled trial, the self-help book improved sleep and reduced the proportion using sleep medications compared to sleep hygiene advice. The self-help book is an efficient low-threshold intervention, which is cheap and easily available for patients suffering from insomnia. Sleep hygiene advice also improved sleep at follow-up, but increased sleep medication use. Thus, caution is warranted when sleep hygiene advice are given as a single treatment.     

The Effects of Magnitude-Based Differential Reinforcement on the Skill Acquisition of Children with Autism

A common recommendation for teaching skills to children with autism is to apply differential reinforcement by reserving high-quality reinforcement for unprompted responses (Sundberg and Partington in Teaching language to children with autism or other developmental disabilities, Behavior Analysts Inc., Pleasant Hill, 1998). Earlier research focuses primarily on schedules or quality of reinforcement, rather than magnitude of reinforcement, when evaluating the use of differential reinforcement in practice. The utility of magnitude-based differential reinforcement may be dependent upon evidence that a learner responds differentially to large and small amounts of reinforcement such that he or she selects the large amount of reinforcement over the small amount of reinforcement and engages in more responses that produce the relatively larger magnitude reinforcement. Three individuals with autism participated in a treatment comparison of differential reinforcement. The manipulation of magnitude of differential reinforcement in a skill acquisition program did not have an appreciable effect on the rate of acquisition for any of the three participants.     

Controlling racial prejudice: social-cognitive goals affect amygdala and stereotype activation

The malleability of stereotyping matters in social psychology and in society. Previous work indicates rapid amygdala and cognitive responses to racial out-groups, leading some researchers to view these responses as inevitable. In this study, the methods of social-cognitive neuroscience were used to investigate how social goals control prejudiced responses. Participants viewed photographs of unfamiliar Black and White faces, under each of three social goals: social categorization (by age), social individuation (vegetable preference), and simple visual inspection (detecting a dot). One study recorded brain activity in the amygdala using functional magnetic resonance imaging, and another measured cognitive activation of stereotypes by lexical priming. Neither response to photos of the racial out-group was inevitable; instead, both responses depended on perceivers' current social-cognitive goal.
