Preference exploration and learning: the role of intensiveness and extensiveness of experience

In this article, the authors partition the construct of experience into intensiveness (i.e., amount) and extensiveness (i.e., breadth) and examine the impact of the two specific types of experience on preference learning. In the first three studies, the authors' theory that experience can be partitioned into intensiveness (i.e., amount) and extensiveness (i.e., breadth) of experience and that extensiveness has a greater impact on preference learning is supported in environments where prior experience is measured. Further, in study 4 they demonstrate that extensiveness or breadth of experience exerts a larger influence on preference learning in an experiment where each unique type of experience is manipulated as well as measured.     

Cross-sectional and longitudinal confirmatory factor models for the german test anxiety inventory: A construct validation

Construct validity of the German Test Anxiety Inventory (TAI-G) was tested in two respects. Firstly, the purported four-dimensional structure of the TAI-G (comprising subscales Emotionality, Worry, Interference, and Lack of Confidence) as well as relations of the test anxiety dimensions to self-efficacy were tested. Secondly, the trait conception of the TAI-G was tested within the framework of Latent State-Trait theory. The TAI-G was given to a student sample (N=302) on three occasions with a time interval of 2 weeks along with a study-specific self-efficacy scale on occasion 1. Dimensionality assumptions as well as relations with self-efficacy were tested using cross-sectional second-order confirmatory factor analysis. The trait conception was tested separately for TAI-G subscales by specifying longitudinal confirmatory factor models (Latent State-Trait models) and by calculating variance proportions of manifest variables (Latent State-Trait coefficients) referring to different sources of systematic variance (person, situation, and method) based on parameter estimates of the models. Results were supportive of both the purported four-dimensional structure and hypothesized relationships to self-efficacy (i.e., acceptable model fit) as well as of the trait conception of test anxiety (i.e., acceptable model fit and high proportion of variance due to person component). Implications for further validation studies were discussed.     

Integrating spatial context learning over contradictory signals: Recency effects in contextual cueing

Contextual cueing is a visual search phenomenon in which memory of global visual context guides spatial attention towards task-relevant portions of the search display. Recent work has shown that the learning processes underlying contextual cueing exhibit primacy effects; they are more sensitive to early experience than to later experience. These results appear to pose difficulties for associative accounts which typically predict recency effects; behaviour being most strongly influenced by recent experience. The current study utilizes trial sequences that consist of two contradictory sets of regularities. In contrast to previous results, robust recency effects were observed. In a second study it is demonstrated that this recency effect can be minimized, but not reversed by systematically manipulating task-irrelevant features of the search display. These results provide additional support for an associative account of contextual cueing and suggest that contextual cueing may, under some circumstances, be more sensitive to recent experience.     

Learned prediction affects body perception

Learning to recognize objects appears to depend critically on extended observation of appearance over time. Specifically, temporal association between dissimilar views of an object has been proposed as a tool for learning invariant representations for recognition. We examined heretofore untested aspects of the temporal association hypothesis using a familiar dynamic object, the human body. Specifically, we examined the role of appearance prediction (temporal asymmetry) in temporal association. In our task, observers performed a change detection task using upright and inverted images of a walking body either with or without previous exposure to a motion stimulus depicting an upright walker. Observers who were exposed to the dynamic stimulus were further divided into two groups dependent on whether the observed motion depicted forward or backward walking. We find that the effect of the motion stimulus on sensitivity is highly dependent on whether the observed motion is consistent with past experience.     

Inclined to see it your way: Do altercentric intrusion effects in visual perspective taking reflect an intrinsically social process?

It has been suggested that some aspects of mental state understanding recruit a rudimentary, but fast and efficient, processing system, demonstrated by the obligatory slowing down of judgements about what the self can see when this is incongruent with what another can see. We tested the social nature of this system by investigating to what extent these altercentric intrusions are elicited under conditions that differed in their social relevance and, further, how these related to self-reported social perspective taking and empathy. In Experiment 1, adult participants were asked to make “self” or “other” perspective-taking judgements during congruent (“self” and “other” can see the same items) or incongruent conditions (“self” and “other” cannot see the same items) in conditions that were social (i.e., involving a social agent), semisocial (an arrow), or nonsocial (a dual-coloured block). Reaction time indices of altercentric intrusion effects were present across all conditions, but were significantly stronger for the social than for the less social conditions. Self-reported perspective taking and empathy correlated with altercentric intrusion effects in the social condition only. In Experiment 2, the significant correlations for the social condition were replicated, but this time with gaze duration indices of altercentric intrusion effects. Findings are discussed with regard to the degree to which this rudimentary system is socially specialized and how it is linked to more conceptual understanding.     

Action–perception coupling in pianists: Learned mappings or spatial musical association of response codes (SMARC) effect?

The principle of common coding suggests that a joint representation is formed when actions are repeatedly paired with a specific perceptual event. Musicians are occupationally specialized with regard to the coupling between actions and their auditory effects. In the present study, we employed a novel paradigm to demonstrate automatic action–effect associations in pianists. Pianists and nonmusicians pressed keys according to aurally presented number sequences. Numbers were presented at pitches that were neutral, congruent, or incongruent with respect to pitches that would normally be produced by such actions. Response time differences were seen between congruent and incongruent sequences in pianists alone. A second experiment was conducted to determine whether these effects could be attributed to the existence of previously documented spatial/pitch compatibility effects. In a “stretched” version of the task, the pitch distance over which the numbers were presented was enlarged to a range that could not be produced by the hand span used in Experiment 1. The finding of a larger response time difference between congruent and incongruent trials in the original, standard, version compared with the stretched version, in pianists, but not in nonmusicians, indicates that the effects obtained are, at least partially, attributable to learned action effects.     

Context-specific control in the single-prime negative-priming procedure

The current paper examines the applicability of the context-specific control principle to the probe selection dependence of negative-priming effects using the single-prime procedure. In a series of experiments, we highlight the applicability of the context-specific control principle, first by illustrating a key result that implicates the role of context-specific control and challenges the contextual similarity principle. Following this, we show the importance of distinct probe contexts in the single-prime negative-priming procedure and report a novel finding that illustrates a learning effect that can occur within an experimental session. Finally, we test the relation of our novel learning effect to a related learning proposal offered by Frings and Wentura (2006), and we demonstrate that the learning involved in context-specific control is not dependent on contingency learning. Overall, the patterns of results highlight the role of context-sensitive memory in controlling how current perception and action are integrated with prior experience.     

Retention beyond the threshold: Test-enhanced relearning of forgotten information

The effect of repeated testing on delayed relearning of paired associates was investigated. Participants learned two lists of Lithuanian-Dutch word pairs until reaching the criterion of one correct recall from long-term memory. In one condition, items subsequently received three post-retrieval study trials and in the other condition items received three post-retrieval test trials. Participants returned one week later for delayed recall and relearning. Post-retrieval test trials resulted in better delayed recall performance than post-retrieval study trials. Moreover, we found that the items that were repeatedly studied or tested one week prior to relearning were relearned faster than a new set of similar (not previously presented) items. Most importantly, items were relearned faster when they had previously been learned under conditions of post-retrieval testing than items learned under conditions of post-retrieval study. Taken together, the results indicate that the benefits of repeated testing are not just limited to conscious recall on a delayed test. Repeated testing during initial learning is also a very effective strategy to enhance delayed relearning.     

The relationship between sustained attention,attentional selectivity,and capacity

The Theory of Visual Attention (TVA; Bundesen, 1990) provides a quantitative account of visual attentional selectivity and capacity but does not include a parameter relating to sustained attention. We conducted two studies to examine the relationship between sustained attention and the TVA parameters relating to selectivity and capacity. In the first study (n=46; mean age=41, SD=10), we investigated the effects of self alerting during a combined whole and partial report task (CombiTVA). In the second study, 70 participants (aged 20–69), performed the CombiTVA and the Sustained Attention to Response Task (Robertson, Manly, Andrade, Baddeley, & Yiend, 1997). The results indicated that attentional selectivity and capacity were unaffected by self alerting, unrelated to sustained attention ability and robust to the adverse effects of time-on-task. These findings are in keeping with the idea of independent functions relating to sustained attention and attentional selectivity and capacity.
