The epistemological objection to modal primitivism

Modal primitivists hold that some modal truths are primitively true. They thus seem to face a special epistemological problem: how can primitive modal truths be known? The epistemological objection has not been adequately developed in the literature. I undertake to develop the objection, and then to argue that the best formulation of the epistemological objection targets all realists about modality, rather than the primitivist alone. Furthermore, the moves available to reductionists in response to the objection are also available to primitivists. I conclude by suggesting that extant theories of the epistemology of modality are not sensitive to the question of primitivism versus reductionism.

     

Development and evaluation of an inventory to assess adult stutterers'' communication attitudes

The purpose of this study was to develop and evaluate a procedure to assess adult stutterers' communication attitudes. To this end, the investigation was divided into two phases. In Phase I, an assessment inventory based on a tripartite attitudinal model was developed and administered to 107 adult stutterers. Reliability and validity of these procedures were examined, and the inventory was refined. In Phase II, reliability and validity of the attitude assessment procedures were reassessed, and the attitudes of 26 stutterers and 56 nonstutterers were examined. Assessment procedures involved a self-report inventory, which obtained ratings of items in 13 situational subscales representing different speaking situations. These situations were rated using four response scales reflecting behavioral, affective, and cognitive aspects of attitude. Situational responding, response scale scores, and response scale interrelationships are examined. Findings are discussed in terms of the potential value of the inventory and future investigations.

Aggression Observation Scale for Group Psychotherapy

An observational scale to record aggressive behaviors, defenses, and interventions that occur during a psychotherapy group has been developed. Content and process items were included. The content items focus on the spoken material and are on a continuum of increasing group members' awareness of and responsibility for their anger. The process items are directed to underlying psychodynamic issues on a continuum from avoiding anger, to indirect and then expression of anger. Leader interventions (responses) are also included. The development of the scale, the Aggression Observation Scale for Group Psychotherapy (AOSGP), is described including pilot testing and reliability and validity findings.     

An analysis of confusion errors in many-to-one matching with temporal and nontemporal samples

In experiment 1, pigeons were trained to match temporal (2, 8, and 10 s of houselight) and location (feeder light, left key, center key illumination) samples to color comparison stimuli. Red choices were correct following the 2-s and feeder light, orange choices were correct following the 8-s and center key, and green choices were correct following the 10-s and left key. Samples that were harder to discriminate (8- vs 10-s, and left vs center key) were mapped onto comparisons that were easy to discriminate (orange vs green), while samples that were easier to discriminate (2- vs 8-s, and feeder light vs left key) were mapped onto comparisons that were hard to discriminate(red vs orange). The pattern of errors for temporal and location samples indicated that these samples were not represented by a common code even though they were associated with the same comparison stimuli. In experiment 2, the same pigeons were trained with visual samples in which samples that were hard to discriminate (triangle vs circle) were mapped onto comparisons that were easy to discriminate (orange vs green), while samples that were easy to discriminate(plus vs triangle) were mapped onto comparisons that were hard to discriminate (red vs orange). Following acquisition of the visual discrimination, the temporal samples were re-introduced and many-to-one training was continued. During delay testing, the pattern of errors for temporal and visual samples was equivalent and consistent with the hypothesis that visual samples were being coded in terms of the duration appropriate for the temporal sample with which it shared a common comparison response. Data from no-sample test sessions ruled out a simple response bias explanation of the data. The properties of common codes for temporal and nontemporal events can be somewhat flexible and more complicated than previously envisaged.

Further evidence for sublexical components in implicit memory for novel words

This study provides further evidence for the notion, proposed by Dorfman (1994), that activation of sublexical components plays an important role in implicit memory for novel words. Priming in an identification task was observed consistently when nonwords were formed out of morphemes; weaker, more variable effects were observed when nonwords were composed of syllables or pseudosyllables. Priming was insensitive to changes in the surface features (type case) of the stimuli and was disrupted by rearrangement of the stimulus components. Results are interpreted in terms of the activation and integration of preexisting sublexical representations and as evidence against the role of newly established episodic or perceptual representations. It is concluded that findings of priming for novel information should not be taken as evidence against an activation view.     

Attention attenuates metacontrast masking

The influence of attention on perceptual awareness was examined using metacontrast masking. Attention was manipulated with endogenous cues to assess the effects on the temporal and spatial parameters of target visibility. Experiment 1 examined the time course of effective masking when the target and mask set were presented at an attended vs. an unattended location. The valid allocation of attention decreased the magnitude of the masking effect (i.e. increased visibility) for approximately 80 ms. Furthermore, even with spatial displacements of the target and mask and center-to-center separations of 1.5 degrees or 2.7 degrees of visual angle (Experiment 2), target visibility was increased when attention was validly allocated. These results indicate that attention influences low-level visual processes to enhance visual awareness.     

Imbalanced word-reading profiles in eighth-graders

This current study introduced a new method to investigate the prevalence and correlates of significant imbalances in the relative accuracy with which eighth-graders read nonwords (e.g., prauma) and exception words (e.g., vaccine). Substantial proportions of students showed imbalanced word-reading profiles, but these were not strongly tied to differences in reading and spelling achievement. Of the students without reading difficulties, 19% had imbalanced word-reading profiles favoring exception words and 17% had imbalanced word-reading profiles favoring nonwords. Of the poor readers, 39% met the criterion for phonological dyslexia (with imbalanced word-reading profiles favoring exception words) and 14% met the criterion for surface dyslexia (with imbalanced word-reading profiles favoring nonwords) in relation to the eighth-grade benchmark readers, but the incidence of these types of dyslexia varied with verbal ability. Of the poor readers with normal verbal ability, 60% were classified as phonological dyslexics and none was classified as surface dyslexic. In students low in verbal ability, surface dyslexia was more common. However, when imbalanced word-reading profiles were defined in relation to fourth-grade reading-level controls, only 12 phonological dyslexics and 1 surface dyslexic were identified. Relatively few cases of either type of developmental dyslexia appeared to be "pure."     

Personality traits and anxiety symptoms: the multilevel trait predictor model

Investigation of relations between personality traits and mental disorders can inform key issues in psychopathology research. However, it has been hindered by extensive correlations among the traits. Building on studies of affect-psychopathology relations (e.g., the tripartite model), an organizational framework is proposed to solve this problem with respect to anxiety pathology. To test the resulting model, associations between four traits (negative emotionality, positive emotionality, anxiety sensitivity, and negative evaluation sensitivity) and four anxiety symptoms (chronic worry, obsessive-compulsive symptoms, panic, and social anxiety) were examined in an undergraduate sample (N=907). Confirmatory factor analyses supported operationalizations of the constructs in this study. Examination of the trait-symptom links using hierarchical multiple regression analyses supported most of the predicted relations. Specifically, negative emotionality emerged as a general predictor that was significantly related to all four symptom dimensions. In contrast, anxiety sensitivity was specific to panic and worry, whereas negative evaluation sensitivity was specific to social anxiety and worry. Finally, positive emotionality was uniquely related to social anxiety. The model accounted for a substantial amount of variance in the symptoms and almost all of the covariation among them.
