Mechanisms of within-session sequential behavior in pigeons

Robert G. Cook et al.

Summary: Correctly and efficiently selecting among options is critical for organizing behavior across different time scales. Understanding the mechanisms underlying the sequential behavior of animals has long been a goal.

Learning and organization of within-session sequences by pigeons (Columba livia)

Muhammad A. J. Qadri et al.

Summary: Most animals, including pigeons, engage in complex activities, which are a combination of simpler actions expressed over a period of time. However, our study found that pigeons did not learn any within-sequence associations among the elements, suggesting that they have difficulty forming sequential representations.

Exemplar-Model Account of Categorization and Recognition When Training Instances Never Repeat

Mingjia Hu et al.

Summary: The study found that in the no-repeat condition, participants showed high accuracy in classifying transfer items, but were unable to effectively distinguish between different levels of prototype distortion in old-new recognition tests. Additionally, when comparing the speed of classification learning between repeated and non-repeated training instances, it was observed that learning was significantly faster in the repeat condition.

Assessing Attention in Category Learning by Animals

Edward A. Wasserman et al.

Summary: Appreciating varied stimuli belonging to different categories requires selective attention to relevant and irrelevant features. Pigeons exhibit a preference for relevant features during category learning, but post-acquisition assessment reveals their attention is more distributed compared to human adults.

Kea (Nestor notabilis) show flexibility and individuality in within-session reversal learning tasks

Monika Laschober et al.

Summary: This study explored the mid-session reversal paradigm in cognitive tasks using kea parrots, demonstrating their quick and flexible responses and individual differences. The birds were able to independently use win-stay/lose-shift strategy and accurately estimate the reversal position, showing diversity in avian cognitive abilities and the importance of considering individual differences when analyzing midsession reversal data.

Constantly Timing, but Not Always Controlled by Time: Evidence From the Midsession Reversal Task

Cristina Santos et al.

Summary: In a study on midsession reversal task, researchers found that choice in frequently changing environments is determined by a combination of temporal and situational cues. Behavior is not solely controlled by time or situational cues, but by a dynamic interaction between the two.

Within-session dynamics of categorical and memory mechanisms in pigeons

Robert G. Cook et al.

Summary: The current experiments explore how pigeons utilize categorical and item-specific mechanisms to learn and solve a novel variation of a task. The results show that categorical control emerges rapidly before item-specific memorization, and both types of control occur within a session, modulated by their time-based relative utility.
