Shadowing and monitoring for selective attention

Although shadowing has been assumed to hold attention strongly (e.g. Hochberg, 1970) this has not been demonstrated, and the incidence of errors and intrusions suggest that it is not as powerful a technique as might have been supposed. An alternative, simpler, technique would be monitoring, but Kahneman (1970) maintains that selectivity fails in the absence of a continuous response. The experiments here compare the shadowing and monitoring tasks when attentional selectivity was required, and when it was not required, and indicate that similar attentional strategies operate during the monitoring and shadowing of brief messages. The shadowing paradigm is criticized in terms of an interaction between the relative resemblance of the stimuli and the shadowing voice. It is not demonstrated that an absolute interaction takes place, but more importantly that relatively greater interference is apparent when the shadower's voice and the stimuli to be shadowed are similar than when they are distinct. It is suggested that low target detections in the unattended message may be an artifact of the processing requirements of the shadowing task.     

Enlarging hope for wholeness: ministry with persons in pain

The author explores the many spiritual ramifications of chronic pain on a person's faith and theology. He suggests that much of contemporary Christian religion, often preoccupied with health and wholeness, may overlook the role chronic pain plays in forming the soul. Making a plea for more cogent ways for the Christian to interrelate a vision of God with the practice of ministry, he expresses the hope that such an enlargement of vision will enhance the sustaining and healing power of pastoral ministry to persons in chronic pain.     

Gender similarities and differences in children's social behavior: finding personality in contextualized patterns of adaptation

This research examined how a contextualist approach to personality can reveal social interactional patterns that are obscured by gender comparisons of overall behavior rates. For some behaviors (verbal aggression), girls and boys differed both in their responses to social events and in how often they encountered them, yet they did not differ in overall behavior rates. For other behaviors (prosocial), gender differences in overall rates were observed, yet girls and boys differed more in their social environments than in their responses to events. The results question the assumption that meaningful personality differences must be manifested in overall act trends and illustrate how gender differences in personality can be conceptualized as patterns of social adaptation that are complex and context specific.     

Confirming statements about pictures of natural scenes: evidence of the processing of gist from eye movements

Combined displays of graphics and text, such as figure captions in newspapers and books, lead to distinctive inspection patterns, or scanpaths. Readers characteristically look very briefly at the picture, and then read the caption, and then look again at the picture. The initial inspection of the picture is the focus of interest in the present experiment, in which we attempted to modify the inspection by giving participants advance knowledge of the subject of a sentence (the cued object) that was to be verified or denied on the basis of whether it correctly described some aspect of the scene shown in the picture. Eye fixations were recorded while the viewers looked at the picture and the sentence in whatever sequence they chose. By allowing viewers to know the subject of the sentence in advance, we asked whether patterns of fixations on the sentence and on the second inspection of the picture would reflect prior knowledge of the focus of the sentence. Providing advance information did not influence eye movements while reading the sentence. It did, however, increase the number of fixations in the initial inspection of the picture, and it also reduced the number and duration of the fixations on the pictures overall. The results suggest that cueing participants to the object allowed increased coding in the initial inspection of the picture, though the benefit of such coding only becomes apparent when the picture is inspected for the second time.

Adolescents’ Text Message Communication and Growth in Antisocial Behavior Across the First Year of High School

This study examined whether adolescents communicate about antisocial topics and behaviors via text messaging and how adolescents’ antisocial text message communication relates to growth in rule-breaking and aggression as reported by youth, parents, and teachers. Participants (n?=?172; 82 girls) received BlackBerry devices configured to capture all text messages sent and received. Four days of text messages during the 9th grade year were coded for discussion of antisocial activities. The majority of participants engaged in at least some antisocial text message communication. Text messaging about antisocial activities significantly predicted increases in parent, teacher, and self-reports of adolescents’ rule-breaking behavior, as well as teacher and self-reports of adolescents’ aggressive behavior. Text message communication may provide instrumental information about how to engage in antisocial behavior and reinforce these behaviors as normative within the peer group.     

Information influences the pattern of eye fixations during sentence comprehension

How does the pattern of eye fixation vary as an informative part of a word is encountered? If the processing of information lags behind the movement of the eyes, then we should expect no variation in the pattern; but if processing is immediate, then the movements of the reader's eyes should correspond to the distribution of information being inspected. An experiment is reported which examined the ways that the text ahead of the point of current fixation can be used to guide the eyes to future fixations, by monitoring fixations during a sentence comprehension task. The patterns of eye fixations upon words with uneven distributions of information (where, for example, words predictable from the sight of their first few letters but not from their last few letters are defined as containing informative beginnings) were observed, and it was found that more and longer fixations were produced when subjects looked at the informative parts of words, particularly at the informative endings of words. The results support the suggestion that eye movements are under the moment-to-moment control of cognitive mechanisms.     

Processing Pitch and Temporal Structures in Music Reading: Independent or Interactive Processing Mechanisms?

Music provides a useful domain in which to study how the different attributes of complex multidimensional stimuli are processed both separately and in combination. Much research has been devoted to addressing how the dimension of pitch and time are co-processed in music listening tasks. Neuropsychological studies have provided evidence for a certain degree of independence between pitch and temporal processing, although there are also many experimental reports favouring interactive models of pitch and temporal processing. Here we extended these investigations by examining the processing of pitch and temporal structures when music is presented in the visual modality (i.e. in the form of music notation). In two experiments, musician subjects were presented with visual musical stimuli containing both pitch and temporal information for a brief amount of time, and they were subsequently required to recall both the pitch and temporal information. In Experiment 1, we documented that concurrent, unattended, pitch and rhythmic auditory interference stimuli disrupted the recall of pitch, but not time. In Experiment 2, we showed that manipulating the tonal structure of the visual presentation stimuli affected the recall of pitch, but not time. On the other hand, manipulating the metrical properties of the visual stimuli affected recall of time, and pitch to a certain extent. Taken together, these results suggest that the processing of pitch is constrained by the processing of time, but the processing of time is not affected by the processing of pitch. These results do not support either strong independence or interactive models of pitch and temporal processing, but they suggest that the processing of time can occur independently from the processing of pitch when performing a written recall task.
