DESCRIPTION:This week we will discuss and debate a very recent paper by Lo
 ckhart and colleagues\, published in Attention\, Perception\, & Psychophys
 ics (2023).\n\nAbstract: “Studies suggest that visual short-term memory 
 (VSTM) is a continuous resource that can be flexibly allocated using proba
 bilistic cues that indicate test likelihood (i.e.\, goal-directed attentio
 nal priority to those items). Previous studies using simultaneous cues hav
 e not examined this flexible allocation beyond two distinct levels of prio
 rity. Moreover\, previous studies have not examined whether there are indi
 vidual differences in the ability to flexibly allocate VSTM resources\, as
  well as whether this ability benefits from practice. The current study us
 ed a continuous report procedure to examine whether participants can use u
 p to three levels of attentional priority to allocate VSTM resources via s
 imultaneous probabilistic spatial cues. Three experiments were performed w
 ith differing priority levels\, cues\, and cue presentation times. Group l
 evel analysis demonstrated flexible allocation of VSTM resources\; however
 \, there was limited evidence that participants could use three goal-direc
 ted priority levels. A temporal analysis suggested that task fatigue\, rat
 her than practice effects\, may interact with item priority. A Bayesian in
 dividual-differences analysis revealed that a minority of participants wer
 e using three levels of attentional priority\, demonstrating that\, while 
 possible\, it is not the predominant pattern of behaviour. Thus\, we provi
 ded evidence that flexible allocation to three attention levels is possibl
 e under simultaneous cuing conditions for a minority of participants. Flex
 ible allocation to three categories may be interpreted as a skill of high-
 performing participants akin to high memory capacity” (Lockhart et al.\,
  2023).\n\nReference: Lockhart\, H.\, Dube\, B.\, MacDonald\, K. J.\, Al-A
