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.

Sign Test for Matched Pairs

Sign Test for Matched Pairs

The sign test for matched pairs offers a robust method for comparing two paired samples, often for the effects of an intervention in one of them. This method is very useful in situations where the underlying distribution of the data is unknown. The test compares two related samples—often pre- and post-treatment measurements on the same subjects—to determine if there are significant differences in their median values.
To conduct the sign test, we first calculate the differences in value between...

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,...

Testing a Claim about Mean: Unknown Population SD

Testing a Claim about Mean: Unknown Population SD

A complete procedure of testing a hypothesis about a population mean when the population standard deviation is unknown is explained here.
Estimating a population mean requires the samples to be approximately normally distributed. The data should be collected from the randomly selected samples having no sampling bias. There is no specific requirement for sample size. But if the sample size is less than 30, and we don't know the population standard deviation, a different approach is used; instead...

Sign Test for Median of Single Population

Sign Test for Median of Single Population

In general, the sign test serves as a nonparametric method to test hypotheses about the median of a single population when the data does not follow a known distribution. This simplicity makes it particularly useful for small sample sizes or when the assumptions of parametric tests cannot be met. The process begins with identifying a null hypothesis, typically stating that the population median equals a specific value. The alternative hypothesis could be that the median is either not equal to,...

Summary

The double-deficit hypothesis accurately models adult reading achievement. Individuals with both phonological awareness and rapid naming deficits show the most severe reading difficulties.

Area of Science:

Neuroscience

Background:

The double-deficit hypothesis suggests combined phonological and naming speed deficits worsen reading difficulties.
This hypothesis has primarily been studied in children.
Adult reading achievement models require further investigation.

Purpose of the Study:

To test the double-deficit hypothesis in an adult sample.
To examine the relationship between phonological awareness, rapid automatized naming (RAN), and adult reading achievement.

Main Methods:

Structural equation modeling was used to analyze data from adult participants.
Participants included parents referred for reading difficulty evaluations.
Reading achievement was assessed in relation to phonological awareness and RAN.

Main Results:

The double-deficit hypothesis was supported in the adult sample.
Stronger phonological awareness and faster RAN were linked to better adult reading achievement.
Individuals with both deficits exhibited significantly lower reading achievement compared to single-deficit or no-deficit groups.

Conclusions:

The double-deficit hypothesis provides a valid framework for understanding adult reading achievement.
Targeting both phonological awareness and rapid naming may be crucial for interventions in adults with reading difficulties.
