Affective Misattribution Following Memory Decisions Does Not Transfer To Interleaved Items, David Grybinas Dec 2019

Affective Misattribution Following Memory Decisions Does Not Transfer To Interleaved Items, David Grybinas

Arts & Sciences Graduate Student Theses and Dissertations

The outcomes of memory search appear to have affective consequences. For instance, during recognition memory tests, concluding that a retrieval probe is from a prior study period (‘old’) leads to higher pleasantness ratings for the probe than concluding it is novel (‘new”). Grybinas, Kantner, and Dobbins (2019) explained this and related findings via a Confirmation of Search (COS) hypothesis that assumes that the affective consequences of successful versus failed episodic retrieval are misattributed to probes used to elicit memory search. While these affective misattributions clearly occur for the memory probes themselves (within-item misattribution), social psychological research has previously shown that …

Attracting And Retaining Young Workforce In Indonesia: Does Person-Organization (P-O) Fit Matter?, Dina Sartika

Makara Human Behavior Studies in Asia

Rooted in the similarity−attraction−attrition paradigm, Cable and Judge’s framework has been one of the leading models in explaining Person−Organization fit. It associates perceived value congruence with employee work attitudes pre and post their entry. This study extends the model and findings by looking at the specific, underlying value dimensions that cause these effects. Drawing on a sample of 800 Indonesian jobseekers, I applied polynomial regression to test the model. Results showed that congruence between personal and organizational social responsibility value was the strongest and most consistent dimension predicting employee job satisfaction and organizational commitment.
