Self-Discrepancy Theory

Self-Discrepancy Theory

One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.

Theory of Attribution II: Kelley's Covariation Theory

Theory of Attribution II: Kelley's Covariation Theory

Attribution theory plays a crucial role in social psychology, helping to explain how individuals interpret the causes of behavior. One prominent model within this field is Harold Kelley's covariation theory, which provides a systematic approach to determining whether internal traits or external circumstances drive a person's actions. The model posits that individuals rely on three key types of information—consensus, consistency, and distinctiveness—to make these judgments.Consensus: Comparing...

Theory of Attribution I: Correspondent Inference Theory

Theory of Attribution I: Correspondent Inference Theory

Correspondent inference theory, proposed by Jones and Davis in 1965, seeks to explain how individuals infer stable personality traits from observed behaviors. It suggests that people attribute actions to underlying dispositions rather than external circumstances, particularly when the behavior appears intentional and socially significant.Voluntary Behavior and Dispositional AttributionAccording to this theory, individuals are more likely to attribute behavior to personal traits when it appears...

Self-Discrepancy and Its Effects

Self-Discrepancy and Its Effects

Self-discrepancy theory explains how people compare their actual self to their ideal and ought selves and how mismatches between these self-guides can lead to emotional distress. Developed by E. Tory Higgins, the theory distinguishes among three components of self-concept: the actual self, the ideal self, and the ought self. These refer respectively to how individuals perceive themselves, how they aspire to be, and how they believe they are obligated to be. Emotional well-being, self-esteem,...

Theory of Romantic Attachment in Adulthood

Theory of Romantic Attachment in Adulthood

Attachment is a long-standing connection or bond with others. While Attachment Theory was conceived in developmental psychology to describe infant-caregiver bonding, it's been extended into adulthood to include romantic relationships.

Frustration and Conflict: Avoidance-Avoidance, Double-Approach Avoidance

Frustration and Conflict: Avoidance-Avoidance, Double-Approach Avoidance

Avoidance-avoidance conflict refers to a psychological situation where a person must choose between two or more unpleasant alternatives. These conflicts are particularly stressful because neither option is desirable. This dilemma is often expressed in sayings like "caught between a rock and a hard place" or "between the devil and the deep blue sea." For instance, individuals who fear dental procedures may find themselves torn between enduring a painful toothache or facing the anxiety of...

Summary

This summary is machine-generated.

Early phonological awareness and rapid naming skills in preschoolers predict elementary reading success. These findings support the double-deficit hypothesis and neuro-developmental theories of reading acquisition.

Background:

Theories of reading development, including Lervag and Hulme's neuro-developmental theory and Wolf and Bowers's double-deficit hypothesis, offer frameworks for understanding reading acquisition.
Longitudinal studies are crucial for tracking developmental trajectories and validating theoretical models of cognitive skills.

Purpose of the Study:

To longitudinally examine the predictive validity of the double-deficit hypothesis and neuro-developmental theory on reading development.
To assess the relationship between early phonological awareness and rapid automatic naming skills with later reading outcomes.

Main Methods:

A longitudinal study followed 130 children from preschool to fifth grade (84 participants completed).
Preschool and kindergarten assessments included tests of end-sound discrimination (phonological awareness; PA) and rapid naming of objects (rapid automatic naming; RAN).
Participants were categorized into four groups based on the double-deficit hypothesis criteria.

Main Results:

Growth curves for reading (word, pseudoword, comprehension) supported the double-deficit hypothesis across the four identified groups.
Early rapid automatic naming (RAN) scores consistently predicted reading abilities throughout elementary school.
Early phonological awareness (PA) and RAN scores were found to be significant predictors of reading development.

Conclusions:

Both phonological awareness and rapid automatic naming are critical predictors of reading success in English-speaking children throughout elementary school.
Early assessments of RAN and PA are more diagnostically informative for predicting reading difficulties than later assessments.
The findings provide empirical support for both the double-deficit hypothesis and neuro-developmental theories in the context of reading acquisition.
