Rapport-building: Chat versus in-person witness interviews

Tactics recommended for rapport-building consist of verbal (e.g., finding common ground or shared experiences) and non-verbal (e.g., affirmations, displaying empathy) behaviours. Most of the research on rapport, however, has examined it in in-person contexts, where both verbal and non-verbal behaviours are present. In this study, we were interested in the effectiveness of rapport-building when conducting online witness interviews via chat, which de-emphasises the use non-verbal rapport behaviours, compared to traditional in-person interviews. Participants (N = 131) experienced a virtual reality (VR) scenario depicting a mock crime and were interviewed either in person or online via the chat function in Skype. Participants perceived rapport more positively when interviewed in person for three measures: attentiveness, trust and respect and expertise. Two other measures, cultural similarity and connected flow, were not perceived differently across interview medium. Participants interviewed online via chat disclosed similar amounts of crime-related information and were just as accurate as participants interviewed in person. We found that in-person interviews yielded better rapport ratings than interviews via chat but were equally productive in terms of the quality of information obtained, as measured by crime-related details and accuracy. If witnesses are to be interviewed via chat, investigators must carefully consider how to compensate for the lack of those non-verbal rapport tactics that influence witnesses' perceptions of attentiveness, trust/respect and investigator's expertise.     

Concurrent fixed-ratio fixed-interval performances in adult human subjects

Two undergraduate males worked for money on a button-pressing task associated with concurrent fixed-ratio fixed-interval schedules of reinforcement. Manipulations of the fixed-ratio requirement produced an interaction between the various fixed-ratio and fixed-interval performances. When the fixed ratio was small, more fixed-interval responding occurred per interval than when the fixed ratio was large. In general, the data were similar to those obtained with lower organisms except that no post-reinforcement pause or ratio strain was seen.     

Adult age comparisons in the processing of event frequency information

The usual superiority in frequency-of-occurrence judgments of younger vs. older subjects was hypothesized to result from greater strategic encoding of the materials conveying frequency information. A subject-paced, visual search task was designed to control nontarget word encoding. Relative frequency judgments for the nontarget word pairs were equally accurate for younger and older subjects, and performance of both groups was above chance. Results suggest that strategic cover-task encoding can induce age differences in incidental frequency processing. Consistent with a nonoptimal as opposed to an optimal view, automatic processes require only minimal capacity for above-chance performance, but additional strategic resources can increase performance. When such additional resources are used more by younger than by older subjects, the former are better in frequency performance.     

A Review of Gerald Caplan's Theory and Practice of Mental Health Consultation

Gerald Caplan's Theory and Practice of Mental Health Consultation (1970), considered to be a classic seminal work in the field of consultation, is reviewed. First, the author presents Caplan's general definition of consultation along with what may be considered the general principles or procedures of consultation. Then the author presents Caplan's procedures and principles as relevant to each type of consultation. Next, each of Caplan's four models of consultation is described. Last, these four models are compared in terms of the professional role of the consultee, the primary goal of consultation, and the target of consultation intervention.     

What does the cook and medley hostility scale measure? Affect, behavior, and attributions in the marital context

The Cook and Medley (1954) Hostility (Ho) scale has been used in several important studies evaluating potential health consequences of hostility. A relative lack of compelling information about the construct validity of the Ho scale, however, has raised concerns about the appropriate interpretation of previous research. In this study, 60 married couples discussed a low conflict topic, a high conflict topic, and then a second low conflict topic. High Ho men responded to the high conflict topic with significant increases in self-reported anger and anxiety and overt hostile behavior, but low Ho men did not. Furthermore, compared to low Ho men, high Ho men blamed their wives more for their usual disagreements on the high conflict topic and saw their disagreement-engendering behavior as more intentional. Among women, Ho scores were weakly related only to overt hostile behavior. Finally, couples consisting of two low Ho persons displayed a uniquely agreeable interactional style.     

Can skilled performers readily change technique? An example, conventional to wave action breaststroke

There has been a paucity of research that has investigated whether skilled performers of a complex sports skill can readily change their technique. This study was designed to investigate whether swimmers skilled in the conventional breaststroke technique could adjust readily to the wave action technique. Nine masters swimmers with well established and stable movement patterns for the conventional technique were coached in the wave action breaststroke technique. The swimmers were videotaped from the side during maximum speed trials of the conventional breaststroke technique before coaching and the wave action technique after ten 45-minute coaching sessions. The amplitude and phase of the waveforms comprising the vertical displacements of the body parts were determined by Fourier analysis. In response to the coaching, the amplitude of the fundamental frequency of the vertex of the head, shoulders, hips, and knees increased significantly (p < 0.01). The percentage of power contained in the fundamental frequency of the shoulder and hip vertical displacements also increased significantly (p < 0.01). All subjects changed the relative phase of the fundamental frequencies of the vertex, shoulder, and hip vertical displacements. It was concluded that in this complex skill, major changes to the low frequency waveforms comprising the motion were achieved readily.     

Child dissociation and the family context

Forty boys and their parents completed measures of dissociation, state anxiety, and perceptions of parental behaviors. Mothers completed a behavior problems checklist about their sons. The results indicated a correspondence between fathers' and sons' dissociation scores. In addition, links were found between parental dissociation, parental inconsistency and rejection, and child dissociation. The findings are discussed in the context of several recently proposed models of the etiology of child dissociative disorders.     

The effects of graphemic,phonetic, and semantic relationships on access to lexical structures

The question of whether or not lexical information is accessed directly from a visual code or by a process of phonetic mediation was investigated in three lexical decision experiments. Phonetic similarity influenced decisions about visually presented words only when they were to be discriminated from orthographically regular nonwords. When consonant strings or random letter strings were used as nonwords, phonetic similarity effects were absent, and graphemic similarity exerted a powerful effect while evidence of semantic priming was found. This pattern was interpreted as evidence of direct lexical access, which is probably the normal processing mode for skilled readers. Phonetic coding, when it occurs, may be a storage strategy rather than a part of the addressing chain for lexical structures.
