Immediate source-monitoring, self-focused attention and the positive symptoms of schizophrenia

Previous research suggests that tendencies to misattribute one's own thoughts to an external source, as assessed by an immediate source-monitoring test, are associated with auditory verbal hallucinations (AVHs). However, recent research suggests that such tendencies are associated instead with symptoms of thought interference. The main aim of the present study was to examine whether such tendencies are differentially associated with different types of thought interference, with AVHs, or with both. It has also been suggested that external misattributions are especially likely to occur with emotionally salient material and if the individual's focus is on the self. These suggestions were also tested. The positive psychotic symptoms of 57 individuals with a diagnosis of schizophrenia were assessed and they then completed the Self-Focus Sentence Completion blank. Immediately after completing each sentence they were asked to indicate to what extent the sentence was their own. The number of sentences that were not rated as completely their own served as their externalisation score. Externalisation scores correlated significantly with the severity of three symptoms: voices commenting, delusions of being controlled, and thought insertion. In a logistic regression analysis, all three of these symptoms were significantly and independently related to externalisation. Externalisation was not associated with either a negative or a neutral self-focus. Thus tendencies to misattribute one's own thoughts to an external source are associated with AVHs and some, but not all, symptoms of thought interference. The importance for externalisation of self-focused attention and of the emotional salience of the elicited thoughts was not supported.     

Thought suppression enhances memory bias for threat material

The current study examined the impact of thought suppression on indices of anxiety, including memory indices (implicit and explicit memory biases) and physiological indices (heart rate). The participants, 81 undergraduates scoring in the top quartile of a self-report measure of trait anxiety, were randomly assigned to one of three experimental groups: thought suppression (TS), thought concentration (TC), and thought wandering (TW). The TC and TW groups were included to control for the effects of effortful processing and exposure to stimuli, respectively. One block of threat words and one block of neutral words were presented under conditions of cognitive load, and participants' physiological responses and memory biases were measured. The thought suppression group exhibited an enhanced overall memory bias for threat words, driven by an elevated explicit memory bias, relative to the other two groups, a result that has implications for ironic processes theory and may inform information-processing models of anxiety.

Social attention in keas, dogs, and human children

Understanding animals’ abilities to cooperate with and learn from each other has been an active field of research in recent years. One important basis for all types of social interactions is the disposition of animals to pay attention to each other—a factor often neglected in discussions and experiments. Since attention differs between species as well as between individuals, it is likely to influence the amount and type of information different species and/or observers may extract from conspecifics in any given situation. Here, we carried out a standardized comparative study on attention towards a model demonstrating food-related behavior in keas, dogs and children. In a series of experimental sessions, individuals watched different conspecific models while searching, manipulating and feeding. Visual access to the demonstration was provided by two observation holes, which allowed us to determine exactly how often and for how long observers watched the model. We found profound differences in the factors that influence attention within as well as between the tested species. This study suggests that attention should be incorporated as an important variable when testing species in social situations.     

BRAND PLACEMENT AND CONSUMER CHOICE: AN IN‐STORE EXPERIMENT

An in‐store experiment was performed to investigate the effects of shelf placement (high, middle, low) on consumers' purchases of potato chips. Placement of potato chips on the middle shelf was associated with the highest percentage of purchases. The results confirm the importance of item placement as a factor in consumers' buying behavior.     

Examining Linguistic Relativity Hypothesis as One of the Main Views on the Relationship Between Language and Thought

One of those features that set human societies apart from animal societies is the use of language. Language is a vital part of every human culture and is a powerful social tool that we master at an early age. A second feature of humans is our ability to solve complex problems. For centuries philosophers have questioned whether these two abilities are related and, if so, what the nature of the relationship between language and thought is. At the beginning of the last century psychologists joined this debate and it is a topic that is currently generating a lot of research. Another factor in the study of language and thought is the role of culture. When we study a language from another country we see that it is not just the words and grammar that are different but the customs and traditions as well. Even the ideas of that culture and the way of dealing with life can be different. There are a number of views on the nature of the relationship between language and thought. But here we are going to explore one of those views, the linguistic relativity hypothesis (LRH), concerning that the language a speaker uses influences the way the speaker thinks.

Evaluating performance in continuous experiments with feedback to subjects

Consider an experiment in which a subject guesses repeatedly at a randomly chosen target on a continuum. To guarantee a positive probability of success, the continuum is partitioned into a finite but large number of segments. The subject is given directional feedback. General guessing strategies are characterized, and an optimal strategy is identified. The hypothesis that the subject's performance can be explained by chance alone is of interest in such experiments. A test is developed based on comparing the subject's performance to expected performance using the optimal strategy. A skill-scoring procedure is developed for assessing a subject's performance in light of the strategy used, and a test based on skill-scoring is advanced.Research by the first author is supported in part by the Air Force Office of Scientific Research under grant AFOSR 77-3180.The authors wish to thank the referees for remarks that led to improvements in both content and clarity.     

Projection in the Face of Centrism: Voter Inferences About Candidates' Party Affiliation in Low-Information Contexts

When are voters more likely to project their own political position onto a candidate for office? We investigate this question by examining the assumed partisanship of a (self-declared) centrist politician, using data from a survey experiment fielded in Canada, the United Kingdom, and the United States. In doing so, we build on the social categorization model as well as recent U.S.-focused political science research on projection and ingroup/outgroup racial divides—extending our analysis to incorporate racial and class similarities/differences across three countries where these divides likely vary in salience. We thus seek: (1) to contribute to research on the inferences citizens draw in nonpartisan elections and low-information contexts generally and (2) to highlight some potential methodological complications of using partisanship-less candidates in vignette experiments. Results suggest that even in the face of a self-declared centrist, voters from across the political spectrum tended to assume shared partisanship in Canada, the United Kingdom, and the United States. Examining projection by ingroup/outgroup divisions indicated that class appears to shape projection across all three countries, but that the racial divide only mattered in the United States. Finally, we also find evidence of counterprojection toward outgroup members—but once again only in the American context.     

Risk factors for infant attrition and low engagement in experiments and free-play

Forty-three 2-month-old infants participated with their mothers in a laboratory study of factors associated with variations in infants' attrition and levels of attention/engagement in a cognitive-perceptual experiment, and in free-play with their mothers. Increased risk of attrition from the experiment was strongly associated with analgesic medication having been administered during labor and with more restricted maternal perceptions of infants' capacities. Attrition rates and levels of engagement varied independently, showing different patterns of association with explanatory variables. Infants' levels of engagement in the experiment and in free-play were correlated across settings and low levels were associated with a lack of maternal identification with the foetus during early pregnancy and more limited maternal perceptions of their infants' capacities, but were not associated with analgesic medication during labor.
