Intentions vs. resemblance: Understanding pictures in typical development and autism

Research has debated whether children reflect on artists’ intentions when comprehending pictures, or instead derive meaning entirely from resemblance. We explore these hypotheses by comparing how typically developing toddlers and low-functioning children with autism (a population impaired in intentional reasoning) interpret abstract pictures. In Experiment 1, both groups mapped familiar object names onto abstract pictures, however, they related the same representations to different 3-D referents. Toddlers linked abstract pictures with intended referents they did not resemble, while children with autism mapped picture-referent relations based on resemblance. Experiment 2 showed that toddlers do not rely upon linguistic cues to determine intended referential relations. Experiment 3 confirmed that the responding of children with autism was not due to perseveration or associative word learning, and also provided independent evidence of their intention-reading difficulties. We argue that typically developing children derive meaning from the social-communicative intentions underlying pictures when resemblance is an inadequate cue to meaning. By contrast, children with autism do not reflect on artists’ intentions and simply relate pictures to whatever they happen to resemble.     

The role of behavioral mind‐sets in goal‐directed activity: Conceptual underpinnings and empirical evidence

The cognitive and motor behavior that people perform in the course of pursuing a goal can induce a mind-set that persists to influence the strategy they use to attain very different goals in unrelated situations. Although the strategies governed by a mind-set are typically applied consciously and deliberately, they are performed without awareness of the reasons for their selection. Research in both social psychology and consumer behavior exemplifies the impact of mind-sets on comprehension, judgments, and decision making, thus providing evidence of the scope and diversity of their effects.     

The representational status of pretence: Evidence from typical development and autism

The question of whether understanding pretend play requires meta‐representational skill was examined among typically developing children and individuals with autism. Participants were presented with closely equated true and false pretence trials in which they had to judge a protagonist's pretend reading of a situation, which either matched or differed from their own. Results showed that individuals' theory of mind abilities determined their performance on false, but not true, pretence trials. These findings imply that meta‐representation is involved when an individual has to make sense of a pretend state of mind that differs from their own, but, crucially, they also show that pretend play can often be understood without meta‐representational competence.     

The link between infant attention to goal‐directed action and later theory of mind abilities

Various studies have shown that infants in their first year of life are able to interpret human actions as goal‐directed. It is argued that this understanding is a precondition for understanding intentional actions and attributing mental states. Moreover, some authors claim that this early action understanding is a precursor of later Theory of Mind (ToM) development. To test this, we related 6‐month‐olds’ performance in an action interpretation task to their performance in ToM tasks at the age of 4 years. Action understanding was assessed using a modified version of the Woodward‐paradigm ( Woodward, 1999 ). At the age of 4 years, the same children were tested with the German version of the ToM scale developed by Wellman and Liu (2004 ). Results revealed a correlation between infants’ decrement of attention to goal‐directed action and their ability to solve a false belief task at the age of 4 years with no modulation by language abilities. Our results indicate a link between infant attention to goal‐directed action and later theory of mind abilities.     

Investigators under influence: How social norms activate goal‐directed processing of criminal evidence

Previous research has shown that exposure to social information can influence behaviour through the automatic activation of goals. In the first study to examine such influences in a legal setting, an experiment with 104 experienced criminal investigators tested the idea that exposure to occupational norms can activate distinct information‐processing goals. As predicted, exposure to norms associated with efficiency (vs. thoroughness) sped up and reduced the depth of investigators' processing of criminal evidence, thus reducing their openness to sequentially late witness evidence. In addition, the goal activation operated outside investigators' awareness, illustrating the insidious cognitive influence of occupational norms. The results are discussed in terms of practical significance and contributions to the goal activation literature and the applied study of criminal investigations.

Infants' mu suppression during the observation of real and mimicked goal‐directed actions

Since their discovery in the early 1990s, mirror neurons have been proposed to be related to many social‐communicative abilities, such as imitation. However, research into the early manifestations of the putative neural mirroring system and its role in early social development is still inconclusive. In the current EEG study, mu suppression, generally thought to reflect activity in neural mirroring systems was investigated in 18‐ to 30‐month‐olds during the observation of object manipulations as well as mimicked actions. EEG power data recorded from frontal, central, and parietal electrodes were analysed. As predicted, based on previous research, mu wave suppression was found over central electrodes during action observation and execution. In addition, a similar suppression was found during the observation of intransitive, mimicked hand movements. To a lesser extent, the results also showed mu suppression at parietal electrode sites, over all three conditions. Mu wave suppression during the observation of hand movements and during the execution of actions was significantly correlated with quality of imitation, but not with age or language level.     

The relationship between mental toughness and cognitive control: Evidence from the item‐method directed forgetting task

Previous research by the authors found that mental toughness, as measured by the Mental Toughness Questionnaire 48 (MTQ48; Clough, P.J., Earle, K., & Sewell, D. [2002]. Mental toughness: the concept and its measurement. In I. Cockerill (Ed.), Solutions in sport psychology [pp. 32–43]. London: Thomson Publishing), was significantly associated with performance on the list‐method directed forgetting task. The current study extends this finding to the item‐method directed forgetting task in which the instruction to Remember or Forget is given after each item in the study list. A significant positive association was found between the correct recognition of Remember words and the emotional control subscale of the MTQ48. No significant associations were observed with other measures of mental toughness or personality. The findings are discussed in terms of the relationship between mental toughness and cognitive control.     

Asymmetrical scepticism towards criminal evidence: The role of goal‐ and belief‐consistency

Previous demonstrations of asymmetrical scepticism (i.e., that investigators perceive evidence inconsistent [vs. consistent] with the focal hypothesis of a case as less reliable) have failed to account for the underlying mechanism. This study examined whether inconsistent evidence is discredited due to its inconsistency with a prior belief or because it conflicts with the goal to reach closure in a case. Police trainees (N = 107) were presented with a homicide case and judged the reliability of incriminating or exonerating evidence while entertaining a ‘guilty’ or ‘innocent’ hypothesis concerning a suspect. Asymmetrical scepticism was observed in the guilty condition, but not in the innocent condition, partially supporting the goal‐consistency explanation. Implications for the organization of criminal investigations are discussed. Copyright © 2010 John Wiley & Sons, Ltd.     

Imitation from 12 to 24 months in autism and typical development: a longitudinal Rasch analysis

The development of imitation during the second year of life plays an important role in domains of sociocognitive development such as language and social learning. Deficits in imitation ability in persons with autism spectrum disorder (ASD) from toddlerhood into adulthood have also been repeatedly documented, raising the possibility that early disruptions in imitation contribute to the onset of ASD and the deficits in language and social interaction that define the disorder. This study prospectively examined the development of imitation between 12 and 24 months of age in 154 infants at familial risk for ASD and 78 typically developing infants who were all later assessed at 36 months for ASD or other developmental delays. The study established a developmental measure of imitation ability and examined group differences over time, using an analytic Rasch measurement model. Results revealed a unidimensional latent construct of imitation and verified a reliable sequence of imitation skills that was invariant over time for all outcome groups. Results also showed that all groups displayed similar significant linear increases in imitation ability between 12 and 24 months and that these increases were related to individual growth in both expressive language and ratings of social engagement but not in fine motor development. The group of children who developed ASD by age 3 years exhibited delayed imitation development compared with the low-risk typical outcome group across all time-points, but were indistinguishable from other high-risk infants who showed other cognitive delays not related to ASD.     

Linking metaphor comprehension with analogical reasoning: Evidence from typical development and autism spectrum disorder

We examined the relationship between metaphor comprehension and verbal analogical reasoning in young adults who were either typically developing (TD) or diagnosed with Autism Spectrum Disorder (ASD). The ASD sample was highly educated and high in verbal ability, and closely matched to a subset of TD participants on age, gender, educational background, and verbal ability. Additional TD participants with a broader range of abilities were also tested. Each participant solved sets of verbal analogies and metaphors in verification formats, allowing measurement of both accuracy and reaction times. Measures of individual differences in vocabulary, verbal working memory, and autistic traits were also obtained. Accuracy for both the verbal analogy and the metaphor task was very similar across the ASD and matched TD groups. However, reaction times on both tasks were longer for the ASD group. Additionally, stronger correlations between verbal analogical reasoning and working memory capacity in the ASD group indicated that processing verbal analogies was more effortful for them. In the case of both groups, accuracy on the metaphor and analogy tasks was correlated. A mediation analysis revealed that after controlling for working memory capacity, the inter-task correlation could be accounted for by the mediating variable of vocabulary knowledge, suggesting that the primary common mechanisms linking the two tasks involve language skills.     

Representing intentions in self and other: studies of autism and typical development

Two experiments were conducted to explore the extent to which individuals with Autism Spectrum Disorder (ASD), as well as young typically developing (TD) children, are explicitly aware of their own and others’ intentions. In Experiment 1, participants with ASD were significantly less likely than age‐ and ability‐matched comparison participants to correctly recognize their own knee‐jerk reflex movements as unintentional. Performance on this knee‐jerk task was associated with performance on measures of false belief understanding, independent of age and verbal ability, in both participants with ASD and TD children. In Experiment 2, participants with ASD were significantly less able than comparison participants to correctly recognize their own or another person’s mistaken actions as unintended, in a ‘Transparent Intentions’ task ( Russell & Hill, 2001 ; Russell, Hill & Franco, 2001 ). Performance on aspects of the Transparent Intentions task was associated with performance on measures of false belief understanding, independent of age and verbal ability, in both participants with ASD and TD children. This study suggests that individuals with ASD have a diminished awareness of their own and others’ intentions and that this diminution is associated with other impairments in theory of mind.     

Self-referential memory in autism spectrum disorder and typical development: Exploring the ownership effect

Owned objects occupy a privileged cognitive processing status and are viewed almost as extensions of the self. It has been demonstrated that items over which a sense of ownership is felt will be better remembered than other items (an example of the “self-reference effect”). As autism spectrum disorder (ASD) is characterised by an a typical self-concept, people with ASD may not demonstrate this “ownership effect”. Two experiments were conducted which replicate and extend Cunningham, Turk, MacDonald, and Macrae (2008). In Experiment 1, neurotypical adults completed a card sorting task and cards belonging to the ‘self’ were better remembered than cards belonging to another person. In Experiment 2, adults with ASD recalled self- and other owned items equally well. These results shed light both on the relation between sense of self and the ownership effect, and the nature of the self-concept in ASD.     

Understanding the mapping between numerical approximation and number words: evidence from Williams syndrome and typical development

All numerate humans have access to two systems of number representation: an exact system that is argued to be based on language and that supports formal mathematics, and an Approximate Number System (ANS) that is present at birth and appears independent of language. Here we examine the interaction between these two systems by comparing the profiles of people with Williams syndrome (WS) with those of typically developing children between ages 4 and 9 years. WS is a rare genetic deficit marked by fluent and well‐structured language together with severe spatial deficits, deficits in formal math, and abnormalities of the parietal cortex, which is thought to subserve the ANS. One of our tasks, requiring approximate number comparison but no number words, revealed that the ANS precision of adolescents with WS was in the range of typically developing 2‐ to 4‐year‐olds. Their precision improved with age but never reached the level of typically developing 6‐ or 9‐year‐olds. The second task, requiring verbal number estimation using number words, revealed that the estimates produced by adolescents with WS were comparable to those of typically developing 6‐ and 9‐year‐olds, i.e. were more advanced than their ANS precision. These results suggest that ANS precision is somewhat separable from the mapping between approximate numerosities and number words, as the former can be severely damaged in a genetic disorder without commensurate impairment in the latter.     

Passion and challenging goals: drawbacks of rushing into goal‐setting processes

This study shows that passion may have a potential downside for setting challenging goals. Hypotheses are developed by drawing on self‐determination theory and goal‐setting theory. Data is collected from a sample of 134 team leaders and hypotheses are tested using ordinary least squares regression analyses. Findings demonstrate that in a project context, team leaders' own competence positively influences their obsessive passion, while their perceptions of team members' competence positively influence their harmonious passion. Goal‐setting speed is included as a mediator in the relationship between passion and degree of goal challenge, proving both harmonious passion and obsessive passion ultimately negatively influence the ability to develop challenging goals because they increase the likelihood of rushing into the goal‐setting process.     

Understanding of emotional experience in autism: insights from the personal accounts of high-functioning children with autism

In this study, the authors investigate emotional understanding in autism through a discourse analytic framework to provide a window into children's strategies for interpreting emotional versus nonemotional encounters and consider the implications for the mechanisms underlying emotional understanding in typical development. Accounts were analyzed for thematic content and discourse structure. Whereas high-functioning children with autism were able to discuss contextually appropriate accounts of simple emotions, their strategies for interpreting all types of emotional (but not nonemotional) experiences differed from those used by typically developing children. High-functioning children with autism were less inclined to organize their emotional accounts in personalized causal-explanatory frameworks and displayed a tendency to describe visually salient elements of experiences seldom observed among comparison children. Findings suggest that children with autism possess less coherent representations of emotional experiences and use alternative strategies for interpreting emotionally evocative encounters. Discussion focuses on the significance of these findings for informing the nature of emotional dysfunction in autism as well as implications for theories of emotional understanding in typical development.     

When goals constrain: Eye movements and memory for goal‐Oriented map study

Perspective goals, such as studying a map to learn a route through an environment or the overall layout of an environment, produce memory congruent with the goal‐directed rather than the studied perspective. One explanation for this finding is that perspective goals guide attention towards actively gathering relevant information during learning. A second explanation is that information is automatically organized into a goal‐congruent spatial model that guides retrieval. Both explanations predict goal‐congruent memory, but only the former one predicts eye movement differences during study. The present experiment investigated the effect of perspective goals on eye movement during map study and the flexibility of resulting spatial memories. Results demonstrate eye movements towards goal‐congruent map elements during learning, and lasting memory effects at test. These findings carry implications for the design of adaptive hand‐held and in‐vehicle navigation interfaces that accommodate for varied user goals. Copyright © 2008 John Wiley & Sons, Ltd.     

We‐commerce: Exploring factors influencing online group‐buying intention in Taiwan from a conformity perspective

Group buying is a relatively new online consumption practice. Consumers negotiate product or service prices with businesses to obtain low prices or an increased number of products. This study investigates factors influencing online group‐buying intention from a conformity perspective. An online survey is used to sample 650 online group buyers in Taiwan. Structural Equation Modelling (SEM) is applied to examine the hypotheses within the theoretical framework. Analytical results indicate that social factors (online recommendations, media recommendations, and personal recommendations) positively affect social influence and online group‐buying intention. Individual factors (compliance and attention‐to‐social‐comparison‐information) positively affect social influence and conformity. Psychological factors (financial risk, performance risk, and social risk) negatively affect online group‐buying intention, and are positively correlated with social influence and conformity. Furthermore, social influence (informational influence and normative influence) are positively correlated with conformity and online group‐buying intention. Social influence and conformity are positively correlated with online group‐buying intention. Finally, implications of analytical findings are discussed.     

Forgetting is effortful: Evidence from reaction time probes in an item-method directed forgetting task

Reaction time (RT) was measured in response to visual detection probes embedded within an item-method directed forgetting paradigm. In Experiment 1, study words were presented individually followed by an instruction to remember (R) or forget (F). Probes were presented at stimulus onset asynchronies (SOAs) of 1,400, 1,800, or 2,600 msec in relation to the study word or memory instruction. After the study trials, a yes-no recognition task measured retention of R and F words. Experiment 2 added a no-word control condition and no-probe catch trials. In both experiments, post-F probe RTs were longer than post-R probe RTs at early SOAs. Confirming that participants attended to the memory instructions, there was a significant directed forgetting effect, with greater recognition of R than of F words. These findings contradict the view that directed forgetting in the item-method paradigm is due to the passive decay of nonrehearsed F items; instead, they are consistent with the view that intentional forgetting in an item-method paradigm occurs via the operation of an active, potentially inhibitory, cognitive process.     

Visuo‐spatial abilities in autism: A review

Individuals with autism show various signs of heightened abilities in visuo‐spatial functioning. First, it is long‐established that they excel on embedded figures and block design tests relative to comparison participants. Second, some evidence suggests that processing global features is affected by inappropriate processing of the constituent elements of a stimulus. Third, they are more accurate than comparison participants in judging the shape of a slanted circle in a context in which ambient visual cues are eliminated. This suggests that their perception of the shape is less influenced by prior knowledge. Fourth, they are fast at searching for feature and conjunctive targets in a visual array. Contrary to earlier reports, however, they are susceptible to visual illusions. Also, they do show evidence of utilising prior knowledge when pairing a colour with an atypically coloured target. Accordingly, we conclude that there is something distinctive about autistic visuo‐spatial functioning, but not necessarily in ways that are predicted by the ‘weak central coherence’ hypothesis.
