The social context of imitation in infancy

Infants increasingly generalize deferred imitation across environmental contexts between 6 and 18 months of age. In three experiments with 126 6-, 9-, 12-, 15-, and 18-month-olds, we examined the role of the social context in deferred imitation. One experimenter demonstrated target actions on a hand puppet, and a second experimenter tested imitation 24h later. When the second experimenter was novel, infants did not exhibit deferred imitation at any age; when infants were preexposed to the second experimenter, all of them did. Imitating immediately after the demonstration also facilitated deferred imitation in a novel social context at all ages but 6 months. Infants' pervasive failure to exhibit deferred imitation in a novel social context may reflect evolutionary selection pressures that favored conservative behavior in social animals.     

Toddlers' use of metric information and landmarks to reorient

Mobile organisms can keep track of spatial location (both their own location and that of objects in the environment) using either an external referent system or one centered on the self and updated by information about movement through space. When the latter system is disabled (e.g., by rapid turning), aspects of the external world must be used to reestablish orientation. Recently, it has been claimed that, both for rats and for human toddlers, reorientation is achieved using a geometric module that accepts only information about the metric properties of the environment (C. R. Gallistel, 1990; L. Hermer & E. S. Spelke, 1994, 1996). In a series of experiments, this paper confirms that geometric information is used for reorientation by young children, but gives reason to doubt that the use of this information is achieved using a module impenetrable to nongeometric information.     

Infants’ coding of location in continuous space

The ability to code location in continuous space is fundamental to spatial behavior. Existing evidence indicates a robust ability for such coding by 12 months, but systematic evidence on earlier origins is lacking. A series of studies investigated 5-month-olds’ ability to code the location of an object hidden in a sandbox, using a looking-time paradigm. In Experiment 1, after familiarization with a hiding-and-finding sequence at one location, infants looked longer at an object being disclosed from a location 12 inches (30 cm) away than at an object emerging from the hiding location, showing they were able to code location in continuous space. In Experiment 2, infants reacted with greater looking when objects emerged from locations 8 inches (20 cm) away from the hiding location, showing that location coding was more finely grained than could be inferred based on the first study. In Experiment 3, infants were familiarized with an object shown in hiding-and-finding sequences at two different locations. Infants looked longer at objects emerging 12 inches (30 cm) away from the most recent hiding location than to emergence from the other location, showing that infants could code location even when events had previously occurred at each location. In Experiment 4, after familiarization with two objects with different shapes, colors, and sounding characteristics, shown in hiding-and-finding sequences in two locations, infants reacted to location violations as they had in Experiment 3. However, they did not react to object violations, that is, events in which the wrong object emerged from a hiding location. Experiment 5 also found no effect of object violation, even when the infants initially saw the two objects side by side. Spatiotemporal characteristics may play a more central role in early object individuation than they do later, although further study is required.     

Why size counts: children's spatial reorientation in large and small enclosures

When mobile organisms are spatially disoriented, for instance by rapid repetitive movement, they must re-establish orientation. Past research has shown that the geometry of enclosing spaces is consistently used for reorientation by a wide variety of species, but that non-geometric features are not always used. Based on these findings, some investigators have postulated a species-universal 'geometric module' that is transcended by the acquisition of spatial language at 6 years. This conclusion has been challenged, however, by findings that children as young as 18 months actually do use features to reorient in larger enclosures than those used in the original experiments. The reason for the room size effect is explored here in five experiments. Collectively, the data on age at which features are first used point to the importance of both restriction of movement in the small space and the fact that features are closer in the small space. In addition, success is seen at younger ages when the target object is adjacent to the feature. These results favor an adaptive combination model of spatial reorientation over a 'module-plus-language' view.     

The role of computer‐aided psychotherapy within an NHS CBT specialist service

To date, the feasibility of computer‐aided psychotherapy as an intervention has only been recognised in primary care practice. The present study sought to evaluate the impact of ‘Beating the Blues’ (BtB), an established computerised cognitive behaviour therapy (CCBT) self‐help programme for the management of anxiety and depression, within an NHS CBT specialist healthcare centre. Of the 555 service users who used BtB as part of routine care, with follow‐up assessment at six to eight weeks, 71% completed all eight sessions. Statistically significant differences on the Beck Depression Inventory‐II (BDI‐II) and Beck Anxiety Inventory (BAI) were found in completer and intention‐to‐treat analyses; 50% of completers achieved reliable change on the BDI‐II and approximately 25% of completers achieved reliable and clinically significant change on both measures. Outcomes were benchmarked against outcomes in studies of routine face‐to‐face CBT. These findings provide evidence that BtB may be of value to service users in secondary mental healthcare centres, alleviating current burdens on public health and therapeutic resources. Future research directions should include examining which factors influence individuals’ decisions to try computer‐aided psychotherapy, which individuals are best suited to using these interventions, and why some users drop out prior to programme completion.     

Generalization of deferred imitation during the first year of life

Infants first generalize across contexts and cues at 3 months of age in operant tasks but not until 12 months of age in imitation tasks. Three experiments using an imitation task examined whether infants younger than 12 months of age might generalize imitation if conditions were more like those in operant studies. Infants sat on a distinctive mat in a room in their home (the context) while an adult modeled actions on a hand puppet (the cue). When they were tested 24 h later, 6-month-olds generalized imitation when either the mat or the room (but not both) differed, whereas 9-month-olds generalized when both the mat and the room differed. In addition, 9-month-olds who imitated immediately also generalized to a novel test cue, whereas 6-month-olds did not. These results parallel results from operant studies and reveal that the similarity between the conditions of encoding and retrieval-not the type of task-determines whether infants generalize. The findings offer further evidence that memory development during infancy is a continuous function.     

Educational risk factors for psychological truancy in Lesotho: a qualitative exploration

A qualitative case study design was used to explore educational risk factors that may contribute to psychological truancy in a Lesotho secondary school. Purposively sampled teachers (n = 4, females = 50%) and pupils (n = 4, females = 75%), who have experience of psychological truancy, took part in a focus group and individual interviews. Inductive content analysis was used to analyse data emanating from the interviews. The findings indicate that pupil–teacher relationships, the use of English as medium of instruction and a lack of resources may be educational risk factors contributing to psychological truancy. Positive pupil–teacher relationships and active classroom engagement are prerequisites for successful and active learning.     

The Impact of Conflict Issues on Fixed-Pie Perceptions, Problem Solving, and Integrative Outcomes in Negotiation

It is argued that a negotiator's fixed-pie perception, cooperative motivation, problem-solving behavior, and integrative outcomes are influenced by the content of the negotiation—the conflict issue. Negotiation involves conflicting interests, conflicting ideas about intellective problems, or conflicting ideas about evaluative problems. Study 1 showed that individuals in a negotiation about interests have a stronger fixed-pie perception and have a lower cooperative motivation than individuals in an evaluative negotiation, with intellective negotiations taking an intermediate position. Study 2 showed that individuals in a negotiation about interests made more trade-offs and reached higher joint outcomes than individuals in an intellective or evaluative negotiation. Study 3 replicated this finding in a field study. The studies bridge insights from negotiation research and decision-making research and show that the conflict issue has important effects on the negotiation process.
