Rhythmic groups and subjective chunks in memory for melodies

Memory for brief melodic phrases was tested using a short-term recognition-memory paradigm. The five-note phrases were rhythmically separated from each other and presented in lists four phrases in length. A single five-note test item followed each list and either corresponded rhythmically to one of the phrases as presented in the list (within items) or to the last three notes of one phrase and the first two notes of the next (across items). Within items were easier than across items. Slow presentation (3 notes/sec) was slightly easier than fast (6 notes/see). The J-shaped serial position curve typical of short-term memory for verbal material was obtained. The results support the position that rhythmic grouping of input determines subjective chunking and memory storage, facilitating the recognition of test items chunked in the same way as list items.     

Recognition of inversions of melodies and melodie contours

Inversions of brief melodies are more difficult to recognize than are transposed repetitions of those melodies. Distinguishing between transposed repetitions and repetitions in which only the melodie contour (the pattern of ups and downs) is repeated is very difficult, as is distinguishing between exact inversions and inversions of the melodie contour.     

Dichotic recognition of musical canons: Effects of leading ear and time lag between ears

A musical canon consists of two melodic lines with the second part copying the first exactly after some time delay. Right-handed adults listened to canons presented dichotically at time delays between the ears of 2, 4, and 8 sec. Presentation rate varied from 1.0 to 4.4 notes/sec in one part. Different groups of subjects heard the canons with the left or the right ear leading. The subject’s task was to tell whether a given stimulus was a canon or not. Control stimuli were noncanons by the same composer. Musically experienced subjects performed better at the task than inexperienced subjects. Short time lags were easier than long, and the effect of lag was more pronounced with the right ear leading. In the light of previous evidence of functional ear asymmetry in music perception, these results suggest that whenever possible subjects use a strategy of selecting out small chunks of the lead-ear melody for short-term memory storage and later comparison with the trailing melody. The auditory system processing information from the right ear is especially good at focusing on small chunks. But this strategy is particularly vulnerable to time lag; hence the interaction of lead ear and time lag.     

Recognition of familiar and unfamiliar melodies in normal aging and Alzheimer’s disease

We tested normal young and elderly adults and elderly Alzheimer’s disease (AD) patients on recognition memory for tunes. In Experiment 1, AD patients and age-matched controls received a study list and an old/new recognition test of highly familiar, traditional tunes, followed by a study list and test of novel tunes. The controls performed better than did the AD patients. The controls showed the “mirror effect” of increased hits and reduced false alarms for traditional versus novel tunes, whereas the patients false-alarmed as often to traditional tunes as to novel tunes. Experiment 2 compared young adults and healthy elderly persons using a similar design. Performance was lower in the elderly group, but both younger and older subjects showed the mirror effect. Experiment 3 produced confusion between preexperimental familiarity and intraexperimental familiarity by mixing traditional and novel tunes in the study lists and tests. Here, the subjects in both age groups resembled the patients of Experiment 1 in failing to show the mirror effect. Older subjects again performed more poorly, and they differed qualitatively from younger subjects in setting stricter criteria for more nameable tunes. Distinguishing different sources of global familiarity is a factor in tune recognition, and the data suggest that this type of source monitoring is impaired in AD and involves different strategies in younger and older adults.     

The influence of negative advertising frames on political cynicism and politician accountability

This research examined the influence of negative political advertising frames on the thoughts and feelings people generate in response to campaign advertising. Preparing and conducting this investigation involved the use of a multiple‐method strategy. Content analysis identified two advertising frames (i.e., candidate theme and ad hoc issue advertisements) and two experiments separately induced political cynicism and politician accountability. Three hundred and sixty people participated in the experimental studies, in which they read and responded, using a thought‐listing technique, to candidate theme or ad hoc issue negative advertisements. Results demonstrated that participants were more likely to generate cynical comments and hold politicians accountable for the country's ills when reading candidate theme advertisements than ad hoc issue advertisements. The results indicate that this contributes to a political climate of cynicism and may function to erode the electorate's overall trust in government.     

A moral justification for killing in self-defence

In the first part of this paper I will argue that for a case to be one of killing in self-defence at least the following three important conditions need to be met: (i) the defender's death must seem to him/her to be imminent; (ii) there must be a choice forced upon the defender between being killed or killing his/her attacker; (iii) the responsibility for (i) and (ii) must be the attacker's. I go on to point out that a lethal use of force which meets conditions (i)—(iii) is thought by most people to be morally permissible. However we believe also that everyone has the right to life and this cannot be taken away under any circumstances. But if this is so, how can we justify one person intentionally killing another? Or to put the point differently: what, in our moral assessment of such cases, are we to claim an attacker has done that is so morally wrong we are prepared to argue that if one of them has to be killed, it is the attacker? I hope to answer this question in the second part of my paper by developing a strand of ethical thought, associated with Kant.     

Pretreatment Correlates of the Therapeutic Alliance in the Chronically Depressed

We examined the relationship between patient characteristics and the working alliance in a multisite trial for chronic depression. Patients treated with the Cognitive Behavioral Analysis System of Psychotherapy (CBASP), alone (n = 169) or combined with nefazodone (n = 198), completed the Working Alliance Inventory during the 2nd week of treatment. Within the CBASP alone group, a history of drug abuse/dependence, lower peak social adjustment over the past five years, and lower current social adjustment predicted a significantly poorer alliance. Within the combination group, male gender and a distancing coping style predicted a significantly poorer alliance. Results should be interpreted with caution since they did not replicate across treatment groups, and the number of significant findings were not much greater than chance expectations.     

Does Engaging in a Group-Based Intervention Increase Parental Self-efficacy in Parents of Preschool Children? A Systematic Review of the Current Literature

As the preschool years are a formative period for long-term physical and mental health, this period is recognised as an important window for early effective intervention. Parenting behaviour is a key factor to target in order to optimise child development. Group-based interventions for parents are considered efficient and cost effective methods of early intervention and have been found to improve child behaviour and adjustment. Self-efficacy is key to behaviour change and as such parental self-efficacy should be a consideration in interventions aimed at influencing parenting behaviour. Therefore, the purpose of this systematic review was to examine the impact of group-based early interventions for parents of preschool children on parental self-efficacy. Nine databases were searched (ASSIA, CINAHL, EMBASE, Maternity and Infant Care, Ovid Medline, PsycINFO, Pubmed, Science Direct and Web of Science). Studies were included if they were a randomised controlled trial of a group-based intervention for parents of preschool children and measured change in parental self-efficacy. Fifteen studies were identified. Although changes in parental self-efficacy following a group-based intervention were noted in the majority of studies reviewed, the methodological quality of the studies included in the review means these findings have to be interpreted with caution; only seven studies were rated to be methodologically adequate. Further research is needed to understand the mechanisms by which these interventions may improve parental self-efficacy. Studies specifically examining the impact of such interventions on paternal self-efficacy are also warranted.
