Getting There (Slowly)

The general foundations for a theory of human sentence processing and the basic goals and questions of the 1960s are argued to be solid and still very relevant today, even if the particular processing model of the time (the clausal model) does not hold up. Today there is considerable agreement that sentence processing is both fast and grammatically controlled from the outset, and that minimal structure and recent attachments are favored across a diverse range of languages. Parsing is not purely bottom-up but instead allows phrases to be postulated before all daughters have been parsed; it works similarly for head-initial and head-final languages. The parser takes as input a rich prosodic/intonational representation which influences processing in ways that extend far beyond use of intonational boundaries as local (juncture) cues. It is argued that psycholinguistic evidence disconfirms the use of prepackaged fully articulated X templates for identifying phrase structure, instead supporting the extended projections of Grimshaw (1991). Further, considerable evidence shows that the processor respects grammatical distinctions among types of dependencies, as indicated by differential processing effects for antecedent-government chains versus binding relations, by the processing difficulty of composite dependencies involving more than one grammatical type of dependency, and by distinctions between deep and surface anaphora. The central problem for future theories of sentence processing is claimed to be the development of theories of sentence interpretation. Various possible approaches are discussed, including parallel computation of alternatives with subsequent selection, a task-driven interpretive system, and underspecification. The question is raised whether sentence-level psycholinguistics is in the middle of a paradigm shift from models with symbolic representations and an intrinsically serial (Von Neumann) architecture to constraint-satisfaction/connectionist models with inherently parallel architectures. Reasons are offered for rejecting current constraint-satisfaction models, including lack of supporting evidence discriminating between constraint-satisfaction and conventional models, serious problems with the use of prepackaged X templates for identifying phrase structure (the only proposal to date for handling syntactic structures in constraint-based models) and an inability to deal with cross-language generalizations. Pure connectionist models are unlikely to fare better in the future for two reasons. They are apparently unable to handle restricted universal quantification (Marcus, 1998)which clearly lies within the capacity of the human sentence processor. Further, competition between alternatives lies at the very heart of such models. Maximal competition should occur in processing fully ambiguous sentences and thus they are predicted to take longer to process than biased or temporarily ambiguous ones (Frazier & Clifton, 1997). But the empirical evidence suggests that fully ambiguous sentences are not systematically harder to process than their disambiguated counterparts.     

Imagination inflation for action events: Repeated imaginings lead to illusory recollections

In two experiments, subjects heard simple action statements (e.g., “Break the toothpick”), and, in some conditions, they also performed the action or imagined performing the action. In a second session that occurred at a later point (10 min, 24 h, 1 week, or 2 weeks later), subjects imagined performing actions one, three, or five times. Some imagined actions represented statements heard, imagined, or performed in the first session, whereas other statements were new in the second session. During a third (test) phase, subjects were instructed to recognize statements only if they had occurred during the first session and, if recognized, to tell whether the action statement had been carried out, imagined, or merely heard. The primary finding was that increasing the number of imaginings during the second session caused subjects to remember later that they had performed an action during the first session when in fact they had not (imagination inflation). This outcome occurred both for statements that subjects had heard but not performed during the first session and for statements that had never been heard during the first session. The results are generally consistent with Johnson, Hashtroudi, and Lindsay’s (1993) source monitoring framework and reveal a powerful memory illusion: Imagining performance of an action can cause its recollection as actually having been carried out.     

Social skill in third and sixth grade children: A moderator of lifetime stressful life events and behavior problems?

We investigated relationships among stressful lifetime life events, social skill, and behavior problems in children. Participants were 159 third graders, 138 sixth graders, and their mothers. Mothers reported on their children's life events, social skill, and behavior problems. Children self-reported on their social skill and behavior problems. Increased numbers of stressful life events significantly predicted increased behavior problems in third and sixth graders. Increased social skill significantly predicted decreased behavior problems in third and sixth graders. Social skill served a stress-protective role for third but not sixth graders; third graders with increased life events and better social skill had fewer behavior problems than their less socially skilled peers. Practical and theoretical implications are discussed, and suggestions for future resilience research are presented.     

Space and holding: Beginning pastoral counseling with incest victims

A case study of an adult victim of incest is considered in terms of space and holding, relying especially on the work of D. W. Winnicott. Reference is made to the effects of sexual abuse as reported in the literature. The situation is considered theologically in terms of evil and rage, holding, and character and faithfulness. Reference is made to Scripture and to character ethics. The pastoral counselor's own character is understood to be his/her primary resource in the therapy process.     

Prospective incidence of first onsets and recurrences of depression in individuals at high and low cognitive risk for depression

Do negative cognitive styles provide similar vulnerability to first onsets versus recurrences of depressive disorders, and are these associations specific to depression? The authors followed for 2.5 years prospectively college freshmen (N = 347) with no initial psychiatric disorders at high-risk (HR) versus low-risk (LR) for depression on the basis of their cognitive styles. HR participants had odds of major, minor, and hopelessness depression that were 3.5-6.8 times greater than the odds for LR individuals. Negative cognitive styles were similarly predictive of first onsets and recurrences of major depression and hopelessness depression but predicted first onsets of minor depression more strongly than recurrences. The risk groups did not differ in incidence of anxiety disorders not comorbid with depression or other disorders, but HR participants were more likely to have an onset of anxiety comorbid with depression.     

The role of cluster B and C personality disturbance in the course of depression: a prospective study

The association between personality disturbance and depression has been noted consistently. Prospective tests of personality's impact on the course of depression, however, are lacking. In a sample of 159 undergraduates who experienced at least one prospective depressive episode, dimensional scores for clusters B and C personality disturbance were examined as prospective predictors of four indicators of the course of depression: severity, episode duration, symptomatic chronicity and number of episodes. Cluster C personality disturbance, characterized by anxious and fearful features, predicted depression chronicity. Cluster B, characterized by dramatic, emotional and/or erratic features, predicted severity and duration of depression. The findings are discussed in terms of the possible mechanisms underlying the effects of clusters B and C, as well as implications for future research.     

Prospective memory and pediatric traumatic brain injury: effects of cognitive demand.

This study investigated the effects of pediatric traumatic brain injury (TBI) on prospective memory. Fourteen children and 14 adolescents with TBI were compared with 25 and 23 noninjured children and adolescents, respectively. Based on a prefrontal model, the cognitive demand on the ongoing component of a prospective-memory task was manipulated. Overall, those with TBI had poorer prospective-memory performance than their noninjured peers. Performance was worse in a high cognitive-demand condition than a low, and younger children performed worse than adolescents. Decreases in performance from the low- to high-demand conditions were not significantly different between the two children's groups but were between the two adolescents' groups. Furthermore, the age and injury effects were reflected in the performances on executive function tests: the Self-ordered Pointing Task (SOPT), and the Stroop Color Word Interference Test. The Tower of London (TOL), which did not produce age or injury effects, was nevertheless found to be an important predictor of performance on the high-demand task in those with TBI. Although previous research has demonstrated impaired prospective memory performance in children with TBI, this study attempted to explain why this might occur, specifically that the prefrontal regions might be implicated.     

Mental representation of symbols as revealed by vocabulary errors in two bonobos (<Emphasis Type="Italic">Pan paniscus</Emphasis>)

Error analysis has been used in humans to detect implicit representations and categories in language use. The present study utilizes the same technique to report on mental representations and categories in symbol use from two bonobos (Pan paniscus). These bonobos have been shown in published reports to comprehend English at the level of a two-and-a-half year old child and to use a keyboard with over 200 visuographic symbols (lexigrams). In this study, vocabulary test errors from over 10 years of data revealed auditory, visual, and spatio-temporal generalizations (errors were more likely items that looked like sounded like, or were frequently associated with the sample item in space or in time), as well as hierarchical and conceptual categorizations. These error data, like those of humans, are a result of spontaneous responding rather than specific training and do not solely depend upon the sample mode (e.g. auditory similarity errors are not universally more frequent with an English sample, nor were visual similarity errors universally more frequent with a photograph sample). However, unlike humans, these bonobos do not make errors based on syntactical confusions (e.g. confusing semantically unrelated nouns), suggesting that they may not separate syntactical and semantic information. These data suggest that apes spontaneously create a complex, hierarchical, web of representations when exposed to a symbol system.

Relationships Among Self,Others, and Persecutors in Individuals With Persecutory Delusions: A Repertory Grid Analysis

The purpose of the current study was to examine the way individuals with persecutory delusions construe the self, others, and their main persecutor with reference to the constructs of malevolence and omnipotence, and examine the extent to which these interpersonal beliefs link to distress, self-esteem, and delusion conviction. Repertory grid methodology was used to explore interpersonal beliefs about malevolence and omnipotence in a sample (N = 30) of individuals with current persecutory delusions (mean age 36.4 years; 62% male and 53% White). Participants also completed measures of emotional distress (depression and anxiety) and self-esteem. The findings suggested that persecutors were construed as more omnipotent and malevolent than both the self and others; others in turn were construed as more omnipotent and malevolent than the self. Beliefs about self as powerful were associated with lower anxiety, depression, and higher self-esteem, and beliefs about persecutors’ omnipotence predicted delusion conviction. As with voices, the concepts of power/omnipotence and malevolence/benevolence appear to be important constructs when seeking to understand the relationship between individuals and their perceived persecutors. These findings support working therapeutically with negative schematic beliefs about self, others, and persecutors, which is consistent with a person-based cognitive therapy model of distressing psychosis.     

Early Pubertal Timing as a Vulnerability to Depression Symptoms: Differential Effects of Race and Sex

Robust evidence supports that girls and boys who experience early pubertal timing, maturing earlier than one’s peers, are vulnerable to developing symptoms of depression. However, it has yet to be clarified whether early pubertal timing confers vulnerability to African American as well as to Caucasian adolescents and whether this vulnerability is specific to depressive symptoms or can be generalized to symptoms of social anxiety. In previous studies, one race or one sex was examined in isolation or sample sizes were too small to examine racial differences. Our longitudinal study consisted of a sample of 223 adolescents (M_age?=?12.42, 54.3 % female, 50.2 % African American, and 49.8 % Caucasian). At baseline, depressive symptoms, social anxiety symptoms, and pubertal timing were assessed by self-report. Nine months later, we assessed depressive symptoms, social anxiety symptoms, body esteem, and stressful life events that occurred between baseline and follow-up. Analyses indicated that early pubertal timing interacted with stressful life events to predict increased symptoms of depression, but only for Caucasian girls and African American boys. Results were found to be specific to depressive symptoms and did not generalize to symptoms of social anxiety. Additionally, there was a significant positive indirect effect of pubertal timing on symptoms of depression through body esteem for Caucasian females.
