Pupil dilation reflects effortful action invigoration in overcoming aversive Pavlovian biases.
Cogn Affect Behav Neurosci
August 2024

"Pavlovian" or "motivational" biases describe the phenomenon that the valence of prospective outcomes modulates action invigoration: Reward prospect invigorates action, whereas punishment prospect suppresses it. The adaptive role of these biases in decision-making is still unclear. One idea is that they constitute a fast-and-frugal decision strategy in situations characterized by high arousal, e.

The necessity of conscious awareness in human learning has been a long-standing topic in psychology and neuroscience. Previous research on non-conscious associative learning is limited by the low signal-to-noise ratio of the subliminal stimulus, and the evidence remains controversial, including failures to replicate. Using functional MRI decoded neurofeedback, we guided participants from both sexes to generate neural patterns akin to those observed when visually perceiving real-world entities (e.

Across three experiments, participants underwent conditioning sequences where the self-referential term I AM (Conditioned Stimulus, or CS+) or a scrambled counterpart M IA (CS-) was paired with either neutral (Unconditioned Stimulus, or US-) or positive attributes (US+). CS and US were presented under subliminal and/or visible conditions. A normalized indicator of affective shift and an explicit self-esteem measure were deployed as outcome measures.

Article Synopsis
- Integrative processing has traditionally been thought to require conscious awareness, but recent studies have challenged this by exploring the idea of subliminal integration.
- The review examines evidence for 10 types of subliminal integration—like arithmetic and multisensory processing—while also addressing potential flaws in how awareness is measured in these studies.
- Ultimately, the review concludes that there is no solid evidence supporting subliminal integration but that the concept of 'unconscious' integration could still hold validity through other non-subliminal methods.
Unconscious knowledge of rewards guides instrumental behaviors via conscious judgments.
Cogn Affect Behav Neurosci
June 2023
Cognitive Psychology Laboratory, Department of Psychology, Babeș-Bolyai University, Cluj-Napoca, Romania.
The demonstration that unconscious learning supports instrumental behaviors (i.e., choosing the stimuli that lead to rewards) is central for the tenet that unconscious cognition sustains human adaptation.
