Forgiveness as a mediator of the relationship between PTSD and hostility in survivors of childhood abuse

It was hypothesised that forgiveness mediates the relationship between PTSD and hostility within a population of adult childhood abuse survivors. Of the three components of forgiveness-self, other, and situation-self and situation forgiveness were posited as potent mediators of the PTSD and hostility relationship. No differences in the mediational role of forgiveness in sexual versus physical abuse and female versus male abuse survivors were hypothesised. As posited, overall forgiveness mediated the PTSD-hostility relationship and the forgiveness of self and situation were strong mediators. The theoretical and applied implications of these findings are discussed.     

A comparison of the differential effects of three different baseline conditions within an ABA1B1 experimental design

The use of the ABA₁B₁ design over recent years in applied behavioural research has prompted many researchers to comment on its strengths and weaknesses (Kazdin, 1973; Kazdin and Bootzin, 1972; Liberman, 1972; Peck and Thorpe, 1971). One major problem is that many different types of non-contingent or no-reinforcement conditions have been used and that different types of baseline conditions may produce different effects. Despite the volume of research using a derivative of this design, surprisingly little is known about the effects of different baseline conditions.The baseline conditions most frequently used include the following: 1. No reinforcement (O'Leary and Becker, 1967; Hall et al., 1972; Aitchison and Green, 1974). 2. Threats (Phillips et al., 1971). 3. Reinforcing other types of behaviour (Ayllon and Azrin, 1965). 4. Equivalent amounts of reinforcement given in baseline and experimental conditions with all baseline reinforcement given non-contingently at the beginning or end of the phase (Wincze et al, 1972; Fernadez et al., 1973; Burchard, 1967). 5. Equivalent amounts of reinforcement in baseline and experimental conditions with baseline reinforcement given non-contingently at regular intervals or randomly throughout the phase (Foxx and Azrin, 1973; Baer and Wolf, 1970).Baer and Wolf (1970) have stated that: ‘Non-contingent reinforcement as a method of extinction has certain characteristics which may make it the method of choice for some experimental designs: especially those designs in which the adult offers reinforcers to a child’. They feel that this method is to be preferred because the total amount of reinforcement can be held constant over all conditions and thus will not be a confounding variable between conditions. However, as Skinner (1948) demonstrated, rate of behaviour can be changed by non-contingent reinforcement when ‘superstitious’ causal relations appear between behaviour and presentation of reinforcement. In effect the rate of behaviour increases because it has accidentally occurred before the presentation of reinforcement and so a connection is established whereby the probability of the behaviour is increased despite the fact that it is not causally related to reinforcement. Morse and Skinner (1957) have said about superstitious conditioning ‘Such effects must always be allowed for in designing experiments on complex behaviour’. Catania and Cutts (1963) and Yelen (1971) have shown that such superstitious conditioning can occur with human subjects.The present experiment employed three groups each trained under the same conditions but with different baseline conditions—1, 4 and 5 above. A multiple baseline design was used in which all possible responses were recorded in a four choice situation so that any accidental contingencies established would be evident.     

Integrating electrophysiology and neuroimaging in the study of human cognition

Noninvasive recordings of electrical and magnetic fields generated by neuronal activity have helped to characterize the temporal sequencing and mechanisms underlying human cognition. Progress is being made toward the goal of localizing the intracranial loci at which many important electromagnetic signals are generated through the use of new analytic techniques and of scalp recordings of electromagnetic activity in neurological patients and through related work in animals. Such methods alone, however, do not yet have the three-dimensional spatial resolution that is necessary in order to identify the intracranial anatomical structures that are involved in the generation of externally recorded activity and, thus, cannot yet inform us with precision about the anatomical substrates of neural events. In comparison, neuroimaging methods, such as positron emission tomography and functional magnetic resonance imaging, can provide higher spatial resolution information about which brain structures are involved in perceptual, motor, and cognitive processes. However, these imaging methods do not yield much information about the time course of brain activity. One promising approach is to combine electromagnetic recordings and functional neuroimaging in order to gain knowledge about the spatiotemporal organization of human cognition. Here we review how electrophysiology and functional neuroimaging can be combined in the study of attention in normal humans.     

Where the Girls (and Women) Are

This paper takes up a theoretical and empirical investigation of how two community-based projects for young women both create safety from community and domestic violence but how, in the process, discourses of multicultural inclusion define one site, and racist discourses of exclusion float through the other site. By relying on two intensive qualitative case studies of community-based organizations for girls, one exclusively White and working class and the other expressly multicultural and antiracist, we try to identify those structures and practices that support feminist, but inadvertently racist, work and those structures and practices that enable, at once, feminist and antiracist consciousness and praxis.     

Affixal homonymy triggers full-form storage, even with inflected words, even in a morphologically rich language

This paper investigates whether affixal homonymy, the phenomenon that one affix form serves two or more semantic/syntactic functions, affects lexical processing of inflected words in a similar way for a morphologically rich language such as Finnish as for morphologically restricted languages such as Dutch and English. For the latter two languages, there is evidence that affixal homonymy triggers full-form storage for inflected words (Bertram, R., Schreuder, R., and Baayen, R. H. (in press). The balance of storage and computation in morphological processing: the role of word formation type, affixal homonymy, and productivity. Journal of Experimental Psychology: Learning, Memory, and Cognition; Sereno and Jongman (1997). Processing of English inflectional morphology. Memory and Cognition, 25, 425-437). Two visual lexical decision experiments show the same pattern for Finnish. Apparently, the substantially richer morphology in Finnish does not prevent full-form storage for inflected words when the affix is homonymic.     

Rights and claims

Conclusion By way of conclusion, I have tried to show that rights do not come from nowhere, that is, rights are not sui generis. They come from claims. Rights do not make claims possible; rather claims make rights possible. For out of claims come claims to rights and from the welter of such claims to rights a legal system is established which, after sifting and refining, accepts some claims to rights and dignifies these as deeds, titles, rights and rejects others; and provides rules enabling persons to exercise their rights. A system of rights and rules thus generated gives one the right to make strong claims. Although having a right is not a condition for making a claim, having a right is necessary to sustain and appraise a claim. Appealing to rights enables us to distinguish weak from strong claims. For rights may sustain or rebut claims though they are not themselves claims.How can we appraise claims? A claim to implies a claim that, the latter being an outcome of the former. If the resulting claim is open to appraisal of the sustain/reject or true/false kind, then it is a claim in a sense other than a primitive cry in the wild. If one can go on to say of a claim that is open to appraisal that one has a right to make such a claim or that one has a strong claim, this is to give favorable, initial appraisal to a claim thus made; and is a claim not in a primitive but in a secondary and ultimately more significant sense.A slightly revised version of a paper read at the Long Island Philosophical Society, May 15, 1971. I wish to thank Lowell Kleinman, Alex Orenstein, Peter Manicas and Karsten Struhl for their helpful criticisms.     

Recollection reduces unitised familiarity effect

Two types of encoding tasks have been employed in previous research to investigate the beneficial effect of unitisation on familiarity-based associative recognition (unitised familiarity effect), namely the compound task and the interactive imagery task. Here we show how these two tasks could differentially engage subsequent recollection-based associative recognition and consequently lead to the turn-on or turn-off of the unitised familiarity effect. In the compound task, participants studied unrelated word pairs as newly learned compounds. In the interactive imagery task, participants studied the same word pairs as interactive images. An associative recognition task was used in combination with the Remember/Know procedure to measure recollection-based and familiarity-based associative recognition. The results showed that the unitised familiarity effect was present in the compound task but was absent in the interactive imagery task. A comparison of the compound and the interactive imagery task revealed a dramatic increase in recollection-based associative recognition for the interactive imagery task. These results suggest that unitisation could benefit familiarity-based associative recognition; however, this effect will be eliminated when the memory trace formed is easily accessed by strong recollection without the need for a familiarity assessment.     

Distinguishing Hope from Optimism and Related Affective States

Three studies examined the conceptual and psychological differences between hope and related mental states. In Study 1, participants provided definitions of hope as well as optimism, want, desire, wish, and the non-anticipatory state of joy; in Study 2, participants wrote about a time when they had experienced each of these states. These definitions and stories were coded for a number of psychological features that were then used to distinguish the different states. Study 3 mapped the differences among the six mental states into a multidimensional conceptual space. Overall, hope is most closely related to wishing but distinct from it. Most important, hope is distinct from optimism by being an emotion, representing more important but less likely outcomes, and by affording less personal control. The importance of combining a folk-conceptual perspective with a more traditional analysis of appraisal for understanding differences among psychological constructs is discussed.     

Implicit bias in impression formation: associations influence the construal of individuating information

The present research investigated the influence of group‐related evaluative associations on the process of impression formation. In particular, we expected the impact of a target's category membership on the construal of ambiguous behaviour to be moderated by perceivers' evaluative associations related to the target category. Associative strength was further expected to have an indirect effect on dispositional inference, mediated by its impact on behaviour identification. Results support both of these assumptions. Moreover, the influence of evaluative associations on impression formation was not moderated by perceivers' motivation to control prejudiced reactions. Rather, motivation to control moderated only the relation between evaluative associations and the explicit endorsement of prejudiced beliefs about the target group in general, such that explicit prejudice endorsement was correlated with evaluative associations only for perceivers low, but not for those high in motivation to control. Implications for prejudice control are discussed. Copyright © 2003 John Wiley & Sons, Ltd.     

Learning to read in children with Williams syndrome

People with Williams syndrome are characterized by linguistic abilities that are higher than their level of intelligence. There is controversy concerning their reading level because there are few studies. The aim of this work was to test reading abilities in a group of school-age children with Williams syndrome. Their performance was contrasted with a control group of the same mental age. Three kinds of tasks were used: word and pseudoword reading, phonological awareness, and naming speed. Results show that the Williams syndrome children performed similarly to control children in reading accuracy but were slower in reading words and pseudowords. They were also slower in the naming speed tasks. These results suggest that Williams syndrome children do not have difficulties in developing grapheme-phoneme decoding but do present some difficulties in developing lexical reading.
