What constitutes globalised evidence? Cultural tensions and critical reflections of the evidence-based movement in New Zealand

The evidence-based movement (EBM) is grounded in a well-intentioned desire to ensure resources are invested in high quality initiatives that generate the intended impact. Nevertheless, recent critiques contest the appropriateness of translating an approach rooted in a medical model to socially complex initiatives. Globalised notions of evidence can also be damaging for programs operating in small, culturally diverse countries with limited resources. Given these polemic views, our aim was to examine local perceptions of the EBM in New Zealand, a small, vibrant, bicultural society with a mix of homegrown and imported programs. Using a snowball sampling approach, 79 professionals working in the education and social sectors completed an anonymous online survey that contained a series of closed and open-ended questions. The results show that although participants positively endorsed a variety of quality evidence markers, traditionally positivist methodological leanings received lower and more varied endorsements compared to more inclusive and pluralistic approaches. Many also expressed concern that the EBM emphasises a narrow and colonised view of evidence that does not align with Māori and Pacific worldviews, and undermines innovation. We discuss the implications as an avenue for advancing intervention and social programming research in an increasingly multicultural and globalised world.     

A developmental study of destereotyping and androgynous activity preferences of tomboys,nontomboys, and males

A study of 210 fourth, sixth, eighth, and tenth graders and adults was conducted to determine developmental trends in both destereotyping of traditionally gender-typed activities and preferences for those activities, and to compare activity preferences of tomboys with other females and with males at different ages. Tenth graders destereotyped less than the other age levels. Additionally, female subjects destereotyped traditionally boys' activities more than girls' activities and more than male subjects. Although nontomboys and boys showed a preference for gender-traditional activities, tomboys preferred traditional girls' and boys' activities equally. Self-defined tomboys do not reject traditionally female activities; instead, they expand their repertoire of activities to include both gender-traditional and nontraditional activities. It is suggested that girls who are able to transcend gender-role behavior in childhood may be the ones who will grow into androgynous adult women.     

Binaural interaction in backward masking

The binaural auditory system exhibits certain advantages over the monaural system when detecting a tonal signal in a background of masking noise. These advantages have been described in detail and are referred to as masking-level differences, or MLDs. It has been demonstrated, for example, that performance in detecting a tonal signal that has been reversed in phase at one ear relative to the other ear is about 15–17 dB better than detection of the same signal in-phase at the two ears when masked by moderately intense masking noise that is in-phase at the two ears. The explanations for this phenomenon fall into two general categories, and both types of explanations are based upon the interaction of the tonal signal and masker when they are added together. In the present paper, data are presented which indicate that an MLD of at least 4–5 dB can be obtained in a binaural masking experiment in which the offset of the tonal signal precedes the onset of the noise masker.     

Effect of “backward” masker fringe on the detectability of pulsed diotic and dichotic tonal signals

The effects of backward masker “fringe” on performance in homophasic and antiphasic masking conditions were investigated. The results of the study indicate that (1) the presence of a backward masker fringe has only a small effect on performance in homophasic masking conditions; (2) under antiphasic masking conditions, the presence of a backward masker fringe improves performance; (3) similar to the results of studies investigating the effects of forward masker fringe, the magnitude of the improvement in performance increases as the duration of the fringe increases; and (4) the magnitude of the improvement caused by the presence of backward masker fringe is considerably smaller than the magnitude of the improvement caused by the forward masker fringe. It appears, then, that the presence of backward masker fringe may provide a baseline or reference phase similar to that which the forward fringe is presumed to provide. The presence of this reference phase after the offset of the signal apparently makes the phase shift associated with the signal-plus-noise waveform more discernible, thus leading to higher detectability. However, for reasons not yet clear, the presence of a baseline or reference phase after the offset of the signal (backward fringe conditions) does not make the signal-plus-noise phase shift as discernible as do either the presence of that same reference phase before the onset of the signal (forward fringe condition) or the presence of that same reference phase both before signal onset and after signal offset (continuous masker condition).     

Social psychology, ‘marital rape exemptions’, and privacy

A 50-state statutory search revealed that variations exist in marital rape exemptions throughout the United States. States handle the question of marital rape in one of three ways: (1) by abolishing the exemption for husbands; (2) by qualifying the exemption; or (3) by allowing the exemption. Although marital rape is a topic that has been largely ignored by social psychology, it is an area ripe for psycho-legal analysis. Possible relationships between social psychology, marital rape exemptions, and privacy are discussed against a background of a psychological jurisprudence.

Group aggregates and individual reliability: The case of verbal short-term memory

Two experiments examined the generalizability of the effects of word length and phonological similarity with visual and auditory presentation in immediate verbal serial ordered recall. In Experiment 1, data were collected from 251 adult volunteers drawn from a broad cross-section of the normal population. Word length and phonological similarity in both presentation modes significantly influenced the group means. However, 43% of the subjects failed to show at least one of the effects, and the likelihood that effects appeared was highly correlated with verbal memory span. In Experiment 2, 40 subjects of the original sample were retested, 20 of whom had failed to show one or more effects in Experiment 1. Whether or not an effect had appeared for individual subjects on the first test session was a poor predictor of whether the effect would appear on retest. Finally, an analysis of subject reports demonstrated that the patterns of experimental data could be accounted for in part by the strategies that subjects reported using, and the effect of strategy was independent of the effect of span. The implications of these findings for theories of verbal short-term memory are discussed.     

Interactive presentation in multitrial free recall

This paper explores whether free recall performance and organization can be facilitated using computer-controlled interactive presentation, where stimulus presentation on Trial N+1 depends on the individual subject’s prior recall history. A series of experiments investigated the effects of two types of response-contingent presentation order manipulations and of selective tagging manipulation designed to highlight the presentation of previously nonrecalled items. An initial experiment using 20-word lists showed no differences among groups, due to a ceiling effect. Two subsequent experiments, using longer lists (30 and 40 words), found that recall and subjective organization were increased by selective tagging and by presentation orders that preserved the subject’s prior order of recall. The results demonstrate that subjects’ previous recall histories contain information that can be used to facilitate recall. The potential of other interactive manipulations is discussed.
