The Implicit Association Test
0 Views •
2023
Source: Julian Wills & Jay Van Bavel—New York University One of the core constructs in social psychology is the notion of an attitude toward an object or person. Traditionally, psychologists measured attitudes by simply asking people to self-report their beliefs, opinions, or feelings. This approach has limitations, however, when measuring socially sensitive attitudes, like racial prejudice, because people are often motivated to self-report unprejudiced, egalitarian beliefs (despite...

Associative Learning

2024
Associative learning is a fundamental concept in behavioral psychology, wherein a connection is established between two stimuli or events, leading to a learned response. This process is critical in understanding how behaviors are acquired and modified. Conditioning, the mechanism through which associations are formed, can be divided into two main types: classical conditioning and operant conditioning, each elucidating different aspects of associative learning. Classical conditioning, also known...

Association Areas of the Cortex

Association areas are regions of the cerebral cortex that do not have a specific sensory or motor function. Instead, they integrate and interpret information from various sources to enable higher cognitive processes such as memory, learning, and decision-making. Some key association areas include the following: Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...

Investigation of Plant Interactions Across Common Mycorrhizal Networks Using Rotated Cores

2019
Most plants within communities likely are interconnected by arbuscular mycorrhizal (AM) fungi, but mediation of plant interactions by them has been investigated primarily by growing plants with versus without mycorrhizas. We present a method to manipulate common mycorrhizal networks among mycorrhizal plants to investigate their consequences for plant interactions.

Training Synesthetic Letter-color Associations by Reading in Color

2014
Reading in color is a new method for training letter-color associations that are typically found only in grapheme-color synesthetes. It involves an implicit form of training that has potential for long-term associative training methods because the training is a byproduct of reading and any text can be colored.
FAQs
The key physical change is the extension of fungal hyphae beyond the root surface. This enlarges the volume of soil explored, allowing the plant-fungus partnership to reach water and minerals that roots alone might not access as effectively. This mechanism links fungal growth with improved resource acquisition.
Phosphorus is a central focus because mycorrhizal activity can improve a plant’s access to this nutrient. The expanded hyphal network explores soil beyond the immediate root zone, potentially strengthening nutrient acquisition. This matters for interpreting plant growth and for evaluating alternatives to heavy reliance on chemical fertilizers.
Carbon exchange sustains the association: plants supply fungi with carbohydrates produced through photosynthesis, while fungal hyphae extend the resource-gathering reach associated with roots. This exchange explains why the relationship can influence both plant nutrition and fungal activity. In biological studies, it connects plant carbon allocation with belowground nutrient acquisition.
Drought and other soil stresses are important conditions when assessing these associations because the relationships can enhance plant tolerance under such pressures. Outcomes may vary across soil or plant combinations, so stress tolerance is a key biological result to investigate when comparing plant performance under different environmental conditions.
Researchers can examine changes in nutrient acquisition, plant growth, stress tolerance, soil structure, and nutrient cycling. These outcomes connect processes at the root-soil interface with wider ecosystem function. Considering several outcomes together is useful because the associations may affect both individual plant performance and the movement and organization of resources in soil.
In sustainable agriculture, mycorrhizal associations are relevant to strategies that seek efficient nutrient use and reduced reliance on chemical fertilizers. In forestry and habitat restoration, they provide a biological context for understanding plant establishment and ecosystem recovery. Their value therefore extends from crop management to broader efforts to support functioning plant communities.
Within biology, these associations help explain how plants interact with their environment rather than functioning as isolated organisms. Their effects on nutrient cycling and soil structure can influence plant community dynamics, while changes in resource access may shape growth under stress. This makes mycorrhizae relevant from root-level exchange to ecosystem processes.
