The Reliability and Validity of the ‘Rejection of Christianity Scale’ among Northern Irish Students

The present aim was to examine the reliability and validity of the ‘Rejection of Christianity Scale’ (Greer & Francis, 1992) among a sample of Northern Irish undergraduate students. A slightly modified version of the ‘Rejection of Christianity Scale’ was administered alongside questions of religiousness and practice. Among a sample of 217 Northern Irish undergraduate students, support was found for the reliability and unidimen‐sionality of the ‘Rejection of Christianity Scale’. The construct validity of the scale was demonstrated with males displaying more signs of rejecting Christianity than females. Furthermore, higher scores on the ‘Rejection of Christianity Scale’ were significantly associated with lower levels of self‐reported religiousness, and lower frequency of church attendance. Limitations of the present study are presented and a further possible modification of the ‘Rejection of Christianity Scale’ is presented.     

The emergence of interest in the ethics of psychological research with humans

We describe the growth of interest in the ethics of research with human participants based on articles abstracted in Psychological Abstracts and PsycLIT. Interest was low and variable until 1974, after which there was a marked increase in the number of articles published. We explain this emergence of ethical interest in terms of the social climate of concern for human rights in the 1960s and 1970s, the 1973 revision of the American Psychological Association's ethical principles, and the development of federal regulation of research with human participants.     

The next generation of psychological autopsy studies: part 2. Interview procedures

The psychological autopsy (PA) is a systematic method of assessing the psychological and contextual circumstances preceding suicide. The method requires interviews with one or more proxy respondents (i.e., informants) of suicide decedents. Procedural challenges that need to be addressed to conduct PA interviews are described in this article and recommendations for meeting these challenges in future PA investigations are made. Procedures addressed include determining the timing of PA interviews after suicide, designing the structure and flow of interviews, selection of proxy respondents, integrating interview data with information gathered from records, and selecting and training interviewers. This methodological article is the second in a two-part series-the first article focused on interview content.     

Word-context effects in word naming and lexical decision

Stanovich and West (1983; West and Stanovich, 1982) demonstrated that lexical decisions to target words preceded by incongruous sentence contexts are inhibited more by these contexts than are naming responses to the same target words. They argued that this difference between the two tasks was due to post-lexical processing at the message level that is effective only in the lexical-decision task. The operations of the mechanism thought to underlie this post-lexical effect also predict that, under certain circumstances, the processing of target words congruous with the sentence context should be facilitated more in lexical decision than in naming. The present naming study together with an earlier lexical-decision study tested and confirmed this prediction for word targets following word contexts. The stimulus-onset asynchrony of context word and target word was also varied. This manipulation clearly affected the magnitude of facilitation, indicating that context-induced attentional processing can facilitate lexical access in word-context studies.     

If you want to get ahead,get a theory

Although Genevan research has provided a detailed analysis of cognitive structures, our knowledge of cognitive processes remains fragmentary. The focus is now not only on macro-development but also on changes occurring in children's spontaneous action sequences in micro-formation. A series of experiments designed to study goal-oriented behavior is in progress. This paper describes the action sequences of 67 subjects between 4;6 and 9;5 years in a block balancing task. It is not a study of children's understanding of a specific notion in physics, but an attempt to pave the way towards understanding the more general processes of cognitive behavior. The analysis focuses on the interplay between the child's action sequences and his implicit theories which the observer infers from the sequences rather than from his verbal comments. Emphasis is placed on the role of counterexamples and on shifts in attention from goal to means. The construction and overgeneralization of ‘theories-in-action’ appear to be dynamic and general processes which are not stage-linked. The results also suggest certain functional rather than structural analogies between the acquisition of physical knowledge and the acquisition of language.     

Working memory, long-term memory, and medial temporal lobe function

Early studies of memory-impaired patients with medial temporal lobe (MTL) damage led to the view that the hippocampus and related MTL structures are involved in the formation of long-term memory and that immediate memory and working memory are independent of these structures. This traditional idea has recently been revisited. Impaired performance in patients with MTL lesions on tasks with short retention intervals, or no retention interval, and neuroimaging findings with similar tasks have been interpreted to mean that the MTL is sometimes needed for working memory and possibly even for visual perception itself. We present a reappraisal of this interpretation. Our main conclusion is that, if the material to be learned exceeds working memory capacity, if the material is difficult to rehearse, or if attention is diverted, performance depends on long-term memory even when the retention interval is brief. This fundamental notion is better captured by the terms subspan memory and supraspan memory than by the terms short-term memory and long-term memory. We propose methods for determining when performance on short-delay tasks must depend on long-term (supraspan) memory and suggest that MTL lesions impair performance only when immediate memory and working memory are insufficient to support performance. In neuroimaging studies, MTL activity during encoding is influenced by the memory load and correlates positively with long-term retention of the material that was presented. The most parsimonious and consistent interpretation of all the data is that subspan memoranda are supported by immediate memory and working memory and are independent of the MTL.     

Early social attention impairments in autism: social orienting, joint attention, and attention to distress

This study investigated social attention impairments in autism (social orienting, joint attention, and attention to another's distress) and their relations to language ability. Three- to four-year-old children with autism spectrum disorder (ASD; n = 72), 3- to 4-year-old developmentally delayed children (n = 34), and 12- to 46-month-old typically developing children (n = 39), matched on mental age, were compared on measures of social orienting, joint attention, and attention to another's distress. Children with autism performed significantly worse than the comparison groups in all of these domains. Combined impairments in joint attention and social orienting were found to best distinguish young children with ASD from those without ASD. Structural equation modeling indicated that joint attention was the best predictor of concurrent language ability. Social orienting and attention to distress were indirectly related to language through their relations with joint attention. These results help to clarify the nature of social attention impairments in autism, offer clues to developmental mechanisms, and suggest targets for early intervention.     

A diffusion model account of normal and impaired readers

Acquired aphasics and dyslexics with even very profound word reading impairments have been shown to perform relatively well on the lexical decision task, but direct contrasts with unimpaired participant's data is often complicated by extremely long reaction times for patient data. The dissociation between lexical decision and word naming performance shown by these patients is of theoretical importance, and here we present an analysis of processing underlying the lexical decision task. We are able to determine what aspects of performance are affected by acquired aphasics in the lexical decision task. We fit lexical decision data from aphasic patients and from normal readers with a sequential sampling model (the diffusion model) that simultaneously considers reaction time and accuracy. This model provides a powerful means of assessing processes involved in impaired and unimpaired lexical decision. Our results suggest that lexical decision may tap impairments at both a linguistic and a nonlinguistic level. These impairments combine to make patients produce the exaggerated lexical decision reaction times typical of neurolinguistic patients: we demonstrate that patients have compromised decision and nondecision processes but that the quality of the information upon which they base their decisions is not much different from that of unimpaired participants.
