When misconduct goes unnoticed: The acceptability of gradual erosion in others’ unethical behavior

Four laboratory studies show that people are more likely to accept others’ unethical behavior when ethical degradation occurs slowly rather than in one abrupt shift. Participants served in the role of watchdogs charged with catching instances of cheating. The watchdogs in our studies were less likely to criticize the actions of others when their behavior eroded gradually, over time, rather than in one abrupt shift. We refer to this phenomenon as the slippery-slope effect. Our studies also demonstrate that at least part of this effect can be attributed to implicit biases that result in a failure to notice ethical erosion when it occurs slowly. Broadly, our studies provide evidence as to when and why people accept cheating by others and examine the conditions under which the slippery-slope effect occurs.     

A longitudinal examination of the transition to symbolic communication in the second year of life

Between 10 and 24 months of age, children progress from communicating through conventional signals to communicating through symbols in a variety of situations. The present study investigates this transition analysing mother–child communication frames and the child's communicative acts, and tracing the developmental changes in both frames and communicative acts. Four children (2 girls, 2 boys) and their mothers were observed longitudinally and extensively, from 10 to 24 months of age, using a multiple case‐study method. Through the detailed investigation of these single cases, clear developmental rajectories were found, showing that conventional frames and representational gestures ‘bridge’ the transition from attentional to symbolic communication. There were significant differences between dyads and children in the developmental trajectories for several frames and communicative acts. The results not only confirm previous findings on the development of verbal and gestural communication, but provide new insights into the transition to symbolic communication in the second year of life, first because of the use of frame analysis and second because of a focus on individual trajectories in development.

Promoting fluency of performance of self‐help tasks with a person with multiple disabilities

A combination of favorite songs and verbal prompts (automatically delivered through portable technology) was used to promote fluency of performance of self‐help tasks in a young man with multiple disabilities. Data indicated that the intervention was effective in reducing the time required by the man to complete the self‐help tasks (dressing and washing). A momentary withdrawal of the prompts after about 6 months from the beginning of the study was accompanied by performance deterioration. Implications of the findings are discussed.

Developmental path between language and autistic‐like impairments: a twin study

Autism spectrum disorders (ASDs) are diagnosed when individuals show impairments in three behavioural domains: communication, social interactions, and repetitive, restrictive behaviours and interests (RRBIs). Recent data suggest that these three sets of behaviours are genetically heterogeneous. Early language delay is strongly associated with ASD, but the basis for this association and the relationship with individual sub‐domains of ASD has not been systematically investigated. In the present study, data came from a population‐based twin sample with language development data at 2–4 years, measured by the MacArthur Communicative Development Inventory (MCDI), and data at 8 years using the Childhood Asperger Syndrome Test (CAST). For the total CAST and the three subscales at 8 years, approximately 300 same‐sex twin pairs were selected as showing extreme autistic‐like traits (ALTs), defined here as pairs in which at least one member of the twin pair scored in the highest 5% of the distribution. Phenotypic analyses indicated that children showing extreme social and communication ALTs (but not the RRBI subscale) at 8 years were below average in language development at 2–4 years. A regression model for selected twin data suggested that genetic influences account for this overlap, but that these effects are only in part mediated by genes that are shared between language and extreme autistic traits.

A proposed typology of personality disorders based on Andras Angyal's system principles: a preliminary note

A classification of personality disorders is proposed based on a typology derived from Andras Angyal's theory of personality, which has two trends (autonomy and homonomy) and two patterns (vicarious living and noncommitment).     

Blinded by anger or feeling the love: how emotions influence advice taking

Across 2 experiments, the authors demonstrate that emotional states influence how receptive people are to advice. The focus of these experiments is on incidental emotions, emotions triggered by a prior experience that is irrelevant to the current situation. The authors demonstrate that people who feel incidental gratitude are more trusting and more receptive to advice than are people in a neutral emotional state, and people in a neutral state are more trusting and more receptive to advice than are people who feel incidental anger. In these experiments, greater receptivity to advice increased judgment accuracy. People who felt incidental gratitude were more accurate than were people in a neutral state, and people in a neutral state were more accurate than were people who felt incidental anger. The results offer insight into how people use advice, and the authors identify conditions under which leaders, policy makers, and advisors may be particularly influential.     

Do we listen to advice just because we paid for it? The impact of advice cost on its use

When facing a decision, people often rely on advice received from others. Previous studies have shown that people tend to discount others’ opinions. Yet, such discounting varies according to several factors. This paper isolates one of these factors: the cost of advice. Specifically, three experiments investigate whether the cost of advice, independent of its quality, affects how people use advice. The studies use the Judge–Advisor System (JAS) to investigate whether people value advice from others more when it costs money than when it is free, and examine the psychological processes that could account for this effect. The results show that people use paid advice significantly more than free advice and suggest that this effect is due to the same forces that have been documented in the literature to explain the sunk costs fallacy. Implications for circumstances under which people value others’ opinions are discussed.     

The ‘Fractionable Autism Triad’: A Review of Evidence from Behavioural,Genetic, Cognitive and Neural Research

Autism is diagnosed on the basis of a triad of impairments in social interaction, communication, and flexible imaginative functions (with restricted and repetitive behaviors and interests; RRBIs). There has been a strong presumption that these different features of the syndrome are strongly intertwined and proceed from a common cause at the genetic, cognitive and neural levels. In this review we examine evidence for an alternative approach, considering the triad as largely ‘fractionable’. We present evidence from our own twin studies, and review relevant literature on autism and autistic-like traits in other groups. We suggest that largely independent genes may operate on social skills/impairments, communication abilities, and RRBIs, requiring a change in molecular-genetic research approaches. At the cognitive level, we suggest that satisfactory accounts exist for each of the triad domains, but no single unitary account can explain both social and nonsocial features of autism. We discuss the implications of the fractionable-triad approach for both diagnosis and future research directions.     

A man with multiple disabilities using a head‐turning response to reduce the effects of his drooling

A man with multiple disabilities was taught to perform a head‐turning response to activate optic sensors embedded in a small spongy structure at his shoulder and produce preferred stimuli. By touching the spongy structure with chin and mouth (i.e., to activate the sensors), the man would clean these areas thus curbing the effects of his drooling. Data showed that the man increased the frequency of his head‐turning responses and reduced drooling effects (chin wetness) through the intervention and a 3‐month follow‐up. Forty university students, who were involved in a social validation assessment, indicated that the intervention was suitable and enjoyable to the man, had a social/educational function, and represented an approach that they supported.

Age-trend-related differences in tasks involving conjunctive probabilistic reasoning

Conjunctive probabilistic reasoning has been studied at different ages to ascertain whether the conjunction fallacy is due to a task demand misinterpretation. Such a misinterpretation might occur because a task that requires a comparison between a superordinate class A and a subordinate class A&B is mistakenly interpreted as requiring a comparison between the two complementary subordinate classes of A (i.e., A&B and A¬B). Children (7- and 10-year-olds) and adults were required to make conjunctive probability judgments about problems for which explicit objective probabilities were provided. The total number of A items was kept constant and the frequencies of the A&B and of the A¬B items varied across problems. When the number of A&B items was smaller than the number of A¬B items, the frequency of congruent responses increased with age. When the number of A&B items was greater or equal to that of the A¬B items, the frequency of correct answers decreased. (PsycINFO Database Record (c) 2008 APA, all rights reserved).
