Cognitive representation of negative numbers

To understand negative numbers, must we refer to positive number representations (the phylogenetic hypothesis), or do we acquire a negative mental number line (the ontogenetic hypothesis)? In the experiment reported here, participants made lateralized button responses to indicate the larger of two digits from the range -9 to 9. Digit pairs were displayed spatially congruent or incongruent with either a phylogenetic or an ontogenetic mental number line. The pattern of decision latencies suggests that negative numbers become associated with left space, thus supporting the ontogenetic view.     

Cognitive representation of auditory space in blind football experts

ObjectivesWe compared the mental representation of sound directions in blind football players, blind non-athletes and sighted individuals.DesignStanding blindfolded in the middle of a circle with 16 loudspeakers, participants judged whether the directions of two subsequently presented sounds were similar or not.MethodStructure dimensional analysis (SDA) was applied to reveal mean cluster solutions for the groups.ResultsHierarchical cluster analysis via SDA resulted in distinct representation structures of sound directions. The blind football players' mean cluster solution consisted of pairs of neighboring directions. The blind non-athletes also clustered the directions in pairs, but included non-adjacent directions. In the sighted participants' structure, frontal directions were clustered pairwise, the absolute back was singled out, and the side regions accounted for more directions.ConclusionsOur results suggest that the mental representation of egocentric auditory space is influenced by sight and by the level of expertise in auditory-based orientation and navigation.     

Cognitive integration of language and memory in bilinguals: semantic representation

Understanding cognitive research on the integration of 2 languages in bilingual memory is difficult because of the different terminology, methodology, analysis, and interpretation strategies that scholars with different backgrounds bring to the research. These studies can be usefully categorized on 2 dimensions: memory for verbal experience versus linguistic knowledge, and systemwise versus pairwise issues. Experimental findings in this area converge on the conclusion that at the word meaning/conceptual level, both episodic and linguistic memory can be characterized as shared at the systems level and at least partly shared at the pairwise translation-equivalent level. Interpretation problems that stem from weak hypothesis testing structure and from covert translation can be minimized by using appropriate design and analysis techniques.     

Creativity. Cognitive, personal, developmental, and social aspects

Although many psychologists have expressed an interest in the phenomenon of creativity, psychological research on this topic did not rapidly expand until after J. P. Guilford claimed, in his 1950 APA presidential address, that this topic deserved far more attention than it was then receiving. This article reviews the progress psychologists have made in understanding creativity since Guilford's call to arms. Research progress has taken place on 4 fronts: the cognitive processes involved in the creative act, the distinctive characteristics of the creative person, the development and manifestation of creativity across the individual life span, and the social environments most strongly associated with creative activity. Although some important questions remain unanswered, psychologists now know more than ever before about how individuals achieve this special and significant form of optimal human functioning.     

Cognitive flexibility in preschoolers: the role of representation activation and maintenance

Preschoolers' lack of cognitive flexibility has often been attributed to perseverative processing. This study investigates alternative potential sources of difficulty such as deficits in activating previously ignored information and in maintaining currently relevant information. In Experiment 1, a new task tapping attentional switching was designed to isolate the difficulty of overriding an initial representation, that is, perseverative processing ('Perseveration' version), and the difficulty of activating a previously ignored representation, that is, activation deficit ('Activation-deficit' version). Three-year-olds' performance suggested that inflexibility may primarily stem from an activation deficit. Control experiments confirmed that the difficulty of the 'Activation-deficit' version could not be attributed to the effect of attraction to novelty. In Experiment 2, 'distraction' errors, alleged to reflect a failure to maintain a relevant representation, and 'perseverative' errors were distinguished. The results highlighted the important role of representation maintenance in flexibility. The present study indicates that preschoolers' lack of cognitive flexibility is multi-determined and prompts us to reconsider the role of perseveration.     

Sexual stereotypes of occupations

This study examined the nature of sex stereotypes of occupations as they exist among college students today. The method of eliciting sexual stereotypes of occupations was distinctive in that three types of rating criteria were used, each emphasizing a different aspect of perception, on the basis of which the ratings of occupations as masculine, feminine, or neutral were subsequently made. The results indicate that sexual stereotypes of occupations are clearly defined and held in agreement by both college men and college women. The study yielded information about the mean rating of each of 129 occupations in terms of its masculinity, femininity, and neutrality.     

Cognitive representation of challenging behaviour among staff working with adults with learning disabilities

Cognitive representations of illness have been identified as a determinant of therapeutic outcomes in a variety of health care settings. This paper describes the development of a Likert-type questionnaire to assess how the concept of challenging behaviour is cognitively represented in staff working with adults with learning disabilities. The Challenging Behaviour Representation Questionnaire (CBRQ) was theoretically derived, drawing on two existing measures: the Illness Perception Questionnaire (IPQ) and the Challenging Behaviour Attributions Scale (CHABA). Items for the questionnaire were generated from responses by 300 direct care staff. The questionnaire shows acceptable levels of internal and external reliability. The questionnaire has face validity and a measure of concurrent validity. There is evidence that challenging behaviour is cognitively represented in care staff in a multi-dimensional way, consistent with other studies in health psychology. This has implications for future staff training in this area.     

Imagining stereotypes away: the moderation of implicit stereotypes through mental imagery.

Research on implicit stereotypes has raised important questions about an individual's ability to moderate and control stereotypic responses. With few strategies shown to be effective in moderating implicit effects, the present research investigates a new strategy based on focused mental imagery. Across 5 experiments, participants who engaged in counterstereotypic mental imagery produced substantially weaker implicit stereotypes compared with participants who engaged in neutral, stereotypic, or no mental imagery. This reduction was demonstrated with a variety of measures, eliminating explanations based on response suppression or shifts in response criterion. Instead, the results suggest that implicit stereotypes are malleable, and that controlled processes, such as mental imagery, may influence the stereotyping process at its early as well as later stages.     

Children's stereotypes of overweight children

The aim of the present study was to assess the content, favourability and generality of perceptions held about overweight children. The research also addressed whether anti‐fat biases change with age and whether they result from a strong association between overweight and bad behaviour, a weak association between overweight and good behaviour or both. Seventy‐three 5‐ to 10‐year‐olds were read aloud a number of short stories containing characters demonstrating high and low athletic, academic, artistic and social abilities. They were then shown eight different pairs of cards; each pair comprised a drawing of an average‐weight and an overweight version of the same child. Participants were then asked to point to the pictures that looked most like the good and bad characters in the stories. The results demonstrated that 5‐ to 8‐year‐olds were significantly less likely to choose an overweight picture to represent the characters with high athletic, academic, artistic and social ability. In contrast, 9‐ to 10‐year‐olds were significantly less likely to choose an overweight figure to represent the characters with high athletic ability, did not differentiate on the basis of weight for the academic and artistic stories, and were significantly more likely to choose an overweight picture as having high social ability.     

When stereotypes get in the way: stereotypes obstruct stereotype-inconsistent trait inferences

There is a growing body of evidence indicating that people spontaneously make trait inferences while observing the behavior of others. The present article reports a series of 5 experiments that examined the influence of stereotypes on the spontaneous inference of traits. Results consistently showed weaker spontaneous trait inferences for stereotype-inconsistent behavioral information than for stereotype-consistent and stereotype-neutral information. Taken together, the current results suggest that specific spontaneous trait inferences become obstructed by inhibitory processes when behavior is inconsistent with an already activated stereotype. These findings are discussed in relation to stereotype maintenance processes and recent models of attribution in social judgment.     

User modeling via stereotypes

This paper addresses the problems that must be considered if computers are going to treat their users as individuals with distinct personalities, goals, and so forth. It first outlines the issues, and then proposes stereotypes as a useful mechanism for building models of individual users on the basis of a small amount of information about them. In order to build user models quickly, a large amount of uncertain knowledge must be incorporated into the models. The issue of how to resolve the conflicts; hot will arise along such inferences is discussed. A system, Grundy, is described that builds models of its users, with the aid of stereotypes, and then exploits those models to guide it in its task, suggesting novels that people may find interesting. If stereotypes are to be useful to Grundy, they must accurately characterize the users of the system. Some techniques to modify stereotypes on the basis of experience are discussed. An analysis of Grundy's performance shows that its user models are effective in guiding its performance.     

The emergence of homegrown stereotypes

Homegrown stereotypes are generalizations that groups develop about their own typical characteristics. They are a distinct class of in-group stereotypes in the contexts and processes that give rise to them, as well as in their consequences for individual group members. The authors develop the concept of homegrown stereotypes and locate the origins of these stereotypes in self-presentation processes. They discuss the accuracy of these stereotypes and consider their similarities to and differences from a number of related phenomena. An examination of homegrown stereotypes highlights the importance of taking into account the impact of in-group, as well as intergroup, dynamics on the production of stereotypes.     

The content of mother stereotypes

Although there is considerable empirical support for the existence of social stereotypes about different types of mothers, the content of those stereotypes is less clear. The purpose of this study was to identify the content of stereotypes related to different types of mothers. Stereotyped attributes of married mothers, stepmothers, divorced mothers, and never married mothers were generated by several samples and combined into one list. A subsequent sample was asked to indicate the percentage of each type of mother possessing each characteristic. The content of mother stereotypes was examined, and the results discussed in light of effects on social interactions, the self-image of women, and future attempts to assess family-related stereotypes.     

Cognitive representation of linear motion: Possible direction and gravity effects in judged displacement

The judged vanishing point of a target undergoing apparent motion in a horizontal, vertical, or oblique direction was examined. In Experiment 1, subjects indicated the vanishing point by positioning a crosshair. Judged vanishing point was displaced forward in the direction of motion, with the magnitude of displacement being largest for horizontal motion, intermediate for oblique motion, and smallest for vertical motion. In addition, the magnitude of displacement increased with faster apparent velocities. In Experiment 2, subjects judged whether a stationary probe presented after the moving target vanished was at the same location where the moving target vanished. Probes were located along the axis of motion, and probes located beyond the vanishing point evidenced a higher probability of a same response than did probes behind the vanishing point. In Experiment 3, subjects judged whether a stationary probe presented after the moving target vanished was located on a straight-line extension of the path of motion of the moving target. Probes below the path of motion evidenced a higher probability of a same response than did probes above the path of motion for horizontal and ascending oblique motion; probes above the path of motion evidenced a higher probability for a same response than did probes below the path of motion for descending oblique motion. Overall, the pattern of results suggests that the magnitude of displacement increases as proximity to a horizontal axis increases, and that in some conditions there may be a component analogous to a gravitational influence incorporated into the mental representation.
