When does word meaning affect immediate serial recall in semantic dementia?

Patients with semantic dementia can show superior immediate recall of words that they still understand relatively well, as compared with more semantically degraded words, suggesting that conceptual knowledge makes a major contribution to phonological short-term memory. However, a number of studies have failed to show such a recall difference, challenging this view. We examined the effect of several methodological factors on the recall of known and degraded words in 4 patients with semantic dementia, in order to investigate possible reasons for this discrepancy. In general, our patients did exhibit poorer recall of the degraded words and made more phonological errors on these items. In addition, set size affected the magnitude of the recall advantage for known words. This finding suggests that semantic degradation influenced the rate of learning in the immediate recall task when the same items were presented repeatedly. The methods used to select known and degraded items also impacted on the recall difference. List length, however, did not affect the advantage for known words. The coherence of items in phonological short-term memory was affected by their semantic status, but not by the length of the material to be retained. The implications of these findings for the role of semantic and phonological representations in verbal short-term memory are discussed.     

The Inventory of Children's Individual Differences: Development and Validation of a Short Version

The development of programmed, actuarial interpretation of personality tests, especially the MMPI, is discussed. The presentation seeks to present a synoptic overview of the topic, including its more important trends, apparent present status, and possible consequences. Several commercially available systems are described, and an example of the output of each of three of them, in interpreting the same MMPI protocol, is presented for comparative illustration.     

Influence of Levels of Abstractness on Reasoning Ability

Judgment by students of faculty effectiveness have relied, for the most part, on subjectively expressed responses to a series of “effectiveness traits” (cues). Simple averaging schemes have summarized the aggregate judgments, often resulting in (a) treating all cues as if they were of equal importance, and (b) inattention to the effects or measurement of individual differences of judges.

Multiple regression was used in this study to derive (empirically) individual cue utilization patterns (i.e., weights) for 10 effectiveness traits. Ss were compared to their subjectively expressed judgment scheme. Results indicate that Ss were moderately successful in expressing their actual cue utilization patterns; however, different judgment schemes were clearly observed.     

Congruence in Sales Force Evaluations: Relation to Sales Force Perceptions of Conflict and Ambiguity

Abstract

This research examined the relationship between salespersons' perceptions of role conflict and role ambiquity from various sources and the degree of agreement between salespeople and sales managers on salesperson performance. Three sources of role ambiguity were found to explain the most variance in performance congruence. Implications for management are discussed.     

Reconsidering Absolute Omnipotence

Philosophical debate about the problem of evil derives, in part, from differing definitions of almighty power or omnipotence. Modern atheists such as John McTaggart, J. L. Mackie, Earl Condee, and Danny Goldstick maintain that an omnipotent God must be able to accomplish anything, even if it entails a contradiction. On this account, the Christian God cannot be omnipotent and benevolent, for a benevolent, omnipotent God would have forced free agents to desist from evil and this prevented the introduction of suffering into the world. It does not matter if the idea of creating free agents that were forced to be good entails a contradiction. On this account, a God who is truly omnipotent can perform contradictory feats.
In this paper, I argue that the atheistic tradition is mistaken. In the first place, even an absolutely omnipotent God could, as an act of benevolence, create a world in which there is suffering. In the second place, I argue that the concept of absolute omnipotence is fatally flawed. An absolutely omnipotent God would lack, in a decisive sense, power. He would be weak rather than strong. So the atheist's argument fails when it is evaluated in light of a more rational account of omnipotence and when it is carefully considered on its own terms.     

Ernst Mach and B. F. Skinner: Their similarities with two traditions for verbal behavior

Ernst Mach is most closely associated with a positivism that demanded a language of close contact with reality. Mach linked this view with the tradition of the quest for an ideal language in which meaning is a property of a word. Logical positivism and the S-R psychology of the early B. F. Skinner also participated in this ideal-language positivism. In addition, Mach showed an affinity with another tradition-a pragmatic-selectionist tradition-although that tradition and Mach's similarities with it were not as well developed. Mach showed no difficulty in jointly maintaining both of these traditions although they have been regarded as deeply incompatible. When the later Skinner adopted a pragmatic selectionism for his later views on verbal behavior, he rejected his earlier views that were aligned with S-R psychology as well as with logical positivism and its sympathizers. Nevertheless, some statements consistent with "meaning is a property of a word" remained for some time in Skinner's writing.     

The Unity of Self at the Interface of the Animal Body and the Cultural System

The self is defined by unity, which must be constructed from multiple inner processes and representations. The unity is more a requirement of social life than of brain activities. The self exists at the interface between the physical body and the social system, which for humans includes culture. The three main aspects of the self are a network of information (sometimes called the self-concept), an interpersonal being (e.g., member of a group or relationship), and executive function (e.g., making decisions). For each of these, multiple inner processes and representations must be integrated to produce the unity of self. Conscious processing plays a key role in this integrative process, because it is a vital means by which different areas of brain and mind exchange information.     

Biases of success rate differences shown in binomial effect size displays

The intent of a binomial effect size display (BESD) is to show "the [real-world] importance of [an] effect indexed by a correlation [r]" (R. Rosenthal, 1994, p. 242) by reexpressing this correlation as a success rate difference (SRD) (e.g., treatment group success rate-control group success rate). However, SRDs displayed in BESDs generally overestimate real-world SRDs implied by correlations of (a) dichotomous X and Y variables (phi coefficients), (b) dichotomous X and continuous Y variables (point-biserial coefficients [rpbs]). and (c) continuous X and Y variables (rxys). Furthermore, overestimation biases are larger for rxys than for rpbs. Differences in the sizes of biases linked to different correlations suggest that BESD SRDs reported for different correlations are not comparable. The stochastic difference index (N. Cliff, 1993: A. Vargha & H. D. Delaney, 2000) is recommended as an alternative to the BESD.
